The 49ers waived Knowles on Thursday, Adam Schefter of ESPN reports.

The Niners swapped out Knowles and Equanimeous St. Brown for fellow wide receivers Marquez Callaway and Andy Isabella on Thursday. Knowles has spent time with the Packers, Vikings and 49ers since going undrafted out of Kansas State in 2023, but he's yet to appear in a regular-season NFL game.

The 49ers released St. Brown on Thursday, Adam Schefter of ESPN reports.

St. Brown lasted all of nine days with the team after signing with the 49ers last week. The team instead signed wide receivers Marquez Callaway and Andy Isabella on Thursday. St. Brown didn't catch a pass in the NFL last regular season.

Williams suffered a calf injury during Thursday's practice, Zack Rosenblatt of The Athletic reports.

The severity of the injury is unknown, but Williams went down during individual drills and remained inside for the remainder of Thursday's session. Williams was named to his third consecutive Pro Bowl last season after logging 37 tackles (25 solo), including 6.0 sacks, across 16 regular-season contests. Some may have considered it a down season for the 27-year-old after he posted 12.0 sacks two seasons prior.

The 49ers signed Isabella to a one-year contract Thursday, Jennifer Lee Chan of NBC Sports Bay Area reports.

Isabella hasn't caught a regular-season pass since the 2022 season with the Cardinals, the team that selected him in the second round of the 2019 Draft. Isabella spent time in the UFL with the St. Louis Battlehawks earlier this year. He should be viewed as a longshot to make the Niners' 53-man roster.

The 49ers signed Callaway to a one-year contract Thursday, Jennifer Lee Chan of NBC Sports Bay Area reports.

The 27-year-old wide receiver appeared in two regular-season games for the Bucs last season but played just five offensive snaps and didn't draw a single target. He hasn't played meaningful regular-season snaps since 2022 with the Saints and should be viewed as a long shot to make the Niners' 53-man roster.

The 49ers signed Bradley to a one-year contract Thursday, Jennifer Lee Chan of NBC Sports Bay Area reports.

Bradley was cut by the Raiders earlier this month after he spent most of last season on Las Vegas' practice squad. Bradley has never appeared in a regular-season NFL game and is merely a camp arm for San Francisco.

The 49ers signed Abdullah to a one-year contract Thursday, Jennifer Lee Chan of NBC Sports Bay Area reports.

Abdullah had a tryout with the Niners on Wednesday and things evidently went well for the veteran running back. He turned 32 years old last month and appeared in 16 regular-season games for the Raiders last season, logging a 66-311-2 rushing line in addition to a 40-261-3 receiving tally on 47 targets. Abdullah will look to win a job behind Christian McCaffrey, Isaac Guerendo and rookie Jordan James this summer.

Cross underwent surgery Thursday to repair a dislocated finger but is expected to be ready for the Seahawks' Week 1 season opener against the 49ers, Ian Rapoport of NFL Network reports.

Despite practicing with the injury, Cross took the opportunity to fix the issue ahead of the start of the regular season. Cross started all 17 regular-season contests for Seattle last season and should once again man left tackle, this time protecting Sam Darnold's blind side.

The Bengals officially signed Fant on Thursday.

Fant, who recorded a 48-500-1 receiving line in 14 regular-season games with the Seahawks in 2024, bolsters a Bengals tight end corps that also includes Mike Gesicki, who caught 65 passes for Cincinnati last season. With star wideouts Ja'Marr Chase and Tee Higgins also around to command plenty of targets, Fant may not initially have a path to steady volume, but the 2019 first-rounder would quickly find himself on the fantasy lineup radar if Gesicki were forced to the sideline at any point this season.

Shavers (ankle) returned to practice Thursday, Sal Capaccio of WGR Sports Radio 550 Buffalo reports.

Shavers injured his ankle last weekend and had to be carted off the field, but he avoided a serious injury and should be ready to roll for the Bills' preseason opener next week. Shavers has an uphill climb to win a roster spot with Buffalo after he spent most of 2024 on the practice squad.
