Mullings (abdomen) has been participating in OTAs.

Mullings was limited at rookie minicamp earlier in May while recovering from core muscle surgery, but the rookie sixth-round pick appears to have shed those limitations at OTAs. He'll be competing in camp against Julius Chestnut and Tyrion Davis-Price for a depth role in a Titans backfield led by Tony Pollard and Tyjae Spears.

Guerendo (knee/ankle) was an active participant at voluntary OTAs, per the 49ers' official site.

Guerendo sustained MCL and ankle sprains in his left leg during San Francisco's regular-season finale, but the 2024 fourth-round pick appears back to full health ahead of mandatory minicamp, which will take place June 10-11. Christian McCaffrey also looks fully healthy after having been limited to four appearances in 2024, which leaves Guerendo competing for No. 2 reps entering Year 2 of his career. The 49ers saw fit to trade Jordan Mason to Minnesota this offseason and let Elijah Mitchell link up with the Chiefs in free agency, though the team did re-sign Patrick Taylor and select Jordan James in the fifth round of the 2025 NFL Draft. Guerendo's combo of athleticism and explosiveness makes him a high-upside backup to McCaffrey, but injuries have been a consistent roadblock for him dating back to college.

Wheeler (knee) is participating in OTAs.

Wheeler signed with the Bears in May of 2024 as an undrafted free agent before landing on IR with a knee injury in late August. Now that he's back on the field, Howard will have a chance to compete for a depth role in a Chicago backfield that's currently led by D'Andre Swift and Roschon Johnson.

Kamara (groin) hasn't been participating in the Saints' voluntary workouts this offseason, Matthew Paras of the New Orleans Times-Picayune reports.

Kamara missed the last three games of the 2024 regular season with a groin injury, but he's presumably past the issue, a notion that will be confirmed when he next takes the field with his teammates, which may arrive when the Saints hold their mandatory minicamp June 10-12. When he's available, Kamara remains entrenched as the team's No. 1 back, but Paras suggests that the backfield pecking order behind that isn't settled. In the running for slotting behind Kamara are Kendre Miller, Devin Neal and Clyde Edwards-Helaire, while Velus Jones, Xazavian Valladay and Marcus Yarns also are in the depth mix for now.

Jacksonville waived Robinson on Thursday, Jeremy Fowler of ESPN.com reports.

Robinson played just five offensive snaps during his rookie season after being selected in the fifth round of the 2024 NFL Draft, and now he's getting cut during the offseason. He'll have to look for his next opportunity to make an impression elsewhere. The battle for the fourth running back slot on the Jaguars' depth chart is now likely between 2025 seventh-rounder LeQuint Allen and UDFA Ja'Quinden Jackson.

The Broncos are hosting Dobbins for a two-day visit Wednesday and Thursday, Zac Stevens of TheDNVR.com reports.

Denver's coaching staff seems to be expressing serious interest in Dobbins, who received an unrestricted free-agent tender from the Chargers in April after racking up a career-best 194 carries for 905 yards (4.6 YPC) and nine scores across 13 regular-season games in 2024. The Broncos selected RJ Harvey in the second round of April's draft, providing the team with a potential starter boasting 4.4 speed, though at 5-foot-8, 205 pounds, the team could have some concerns about the UCF product's ability to hold up to workhorse volume at the NFL level. Dobbins has durability concerns of his own due to his injury history, but Broncos coach Sean Payton has deployed a running back tandem to great success in the past, and Dobbins' rushing style could make him a fitting complement to Harvey.

Swift said Tuesday at mandatory minicamp that he's "being very critical about how I played last year" and is "excited about this year" under new head coach Ben Johnson, Patrick Finley of the Chicago Sun Times reports.

The first season of Swift's three-year, $24 million deal with the Bears disappointed compared to expectations, as he finished with just 959 rushing yards and six touchdowns despite playing all 17 regular-season games and handling a career-high 253 carries. He averaged just 3.8 YPC in 2024 after having combined for 4.6 YPC across the first four years of his NFL career. As such, it was somewhat surprising to see Chicago fail to add notable backfield competition in free agency or the 2025 NFL Draft. Rookie seventh-round pick Kyle Monangai joins Roschon Johnson as a depth option, but Swift seems destined to reprise a starting role. With the benefit of a much-improved O-line and Johnson's promising offensive scheme, Swift will be in tremendous position to improve upon his 2024 stats if he sees a similar amount of opportunities. Johnson, who was Swift's offensive coordinator during his final season in Detroit in 2022, called the running back a "fierce competitor" and praised his willingness to "find a way to put his shoulder down and move the pile."

Corum (forearm) has been an active participant at OTAs, per the Rams' official site.

Corum suited up for all 17 regular-season games during his uneventful rookie campaign but missed both of Los Angeles' playoff bouts due to a fractured forearm suffered Week 18. The 2024 third-round pick now seems back to full health, though heading into Year 2 he faces new competition from rookie fourth-round pick Jarquez Hunter for the backup role behind Kyren Williams. As a rookie, Corum rushed just 58 times for 207 yards (3.6 YPC) while failing to reach the end zone, adding just seven catches (on eight targets) for 58 yards. Hunter boasts big-play speed that could make him a fitting complement to Williams, so Corum will need to show more this offseason to avoid being stuck in a negligible role again.

Mason (ankle) participated in on-field drills during OTAs on Tuesday, per the Vikings' official site.

Mason appears fully recovered from the high-ankle sprain that forced him to miss the final five regular-season games of his breakout 2024 campaign in San Francisco. The 26-year-old impressed out of the gate last year with Christian McCaffrey unavailable for the 49ers, rushing 134 times for 685 yards (5.1 YPC) and three scores during the team's first eight games, before injuries of his own popped up. Aaron Jones inked a two-year extension with Minnesota this offseason and still projects as the team's starter, but in the interest of keeping the 30-year-old fresh, Mason will be a candidate to push for a significant backfield split. Boasting a far larger frame at 5-foot-11, 223 pounds, Mason also seems the favorite for short-yardage and goal-line work.

Walker (ankle) is participating in Seattle's voluntary OTAs, per the team's official site.

Walker is pictured among teammates participating in the Seahawks' second week of OTAs, which began Monday. Now healthy and heading into the final year of his rookie deal, Walker's situation in Seattle's backfield remains familiar. If he can avoid the injury bug and stay 100 percent healthy, something Walker has struggled to accomplish through his first three seasons in the NFL, he looks entrenched as the starter ahead of Zach Charbonnet. The arrival of new starting quarterback Sam Darnold could allow this offense to take a step forward in 2025, while new offensive coordinator Klint Kubiak's scheme, which focuses on zone rushes, is an ideal fit for Walker's tough running style and explosiveness. Health remains the most pivotal factor in prognosticating Walker, but if he's able to break the pattern of lower-body injuries hampering him, it won't be surprising if the 2022 second-round pick outperforms his ADP in 2025 fantasy drafts.
