Williamson was removed from his start Tuesday against Atlanta with an apparent injury, Gordon Wittenmyer of The Cincinnati Enquirer reports.

Williamson appeared to be grabbing at his left elbow after making a pitch in the second inning of Tuesday's contest. The specifics of his injury won't be known until the Reds are able to take a closer look at him, but the 26-year-old southpaw may be at risk of missing even more time after sitting out the first five months of the season due to a shoulder issue.

Nationals manager Dave Martinez said Tuesday that Cavalli (elbow) will continue to work through his throwing program but won't pitch in games before the end of the season, Andrew Golden of The Washington Post reports.

The right-hander began the season on the injured list while completing his recovery from Tommy John Surgery in May 2023, but a "dead arm" phase over the summer derailed his rehab assignment. Cavalli will continue to build up his arm over the final weeks of the regular season, but he'll head into 2025 with plenty of uncertainty coming off consecutive lost seasons.

Dodgers manager Dave Roberts said Tuesday that Gonsolin (elbow) will make another rehab appearance with Triple-A Oklahoma City before potentially returning from the 60-day injured list, Fabian Ardaya of The Athletic reports.

The right-hander has two rehab outings under his belt with Oklahoma City, and he allowed two runs on five hits and a walk over 2.2 innings during the most recent appearance Sunday. Los Angeles is in need of rotation help, but that doesn't necessarily mean Gonsolin will start once he completes his rehab program from last September's Tommy John surgery. There's also no guarantee the 30-year-old is included on the playoff roster.

Reds manager David Bell said Tuesday that Lodolo (finger) won't return from the 15-day injured list before the end of the season, Mark Sheldon of MLB.com reports.

The left-hander will end up missing the final five-plus weeks of the season due to the sprained finger he sustained Aug. 22 against the Pirates. Lodolo should have plenty of time to get healthy before the start of spring training and closes out the 2024 season with a 4.76 ERA, 1.20 WHIP and 122:37 K:BB over 115.1 innings (21 starts).

Cubs manager Craig Counsell announced Tuesday that Steele (elbow) will be reinstated from the 15-day injured list to start Wednesday against the Athletics, Ryan Herrera of AllCHGO.com reports.

The left-hander landed on the shelf after experiencing elbow tendinitis following his last start Aug. 27 in Pittsburgh, and he'll be back with the Cubs for the final week and a half of the campaign. If Chicago sticks to a five-man rotation, Steele tentatively lines up for three starts before the end of the regular season. The 29-year-old has a 3.09 ERA, 1.09 WHIP and 131:34 K:BB across 128 innings this season.

Senga (calf) threw a bullpen session and did some pitchers' fielding practice drills Tuesday, Laura Albanese of Newsday reports.

Mets manager Carlos Mendoza said afterward that it remains possible Senga will return sometime during the final week of the regular season. If that happens, it will almost certainly have to be in a relief role, as Senga does not have time to get stretched back out to start.

Greene (elbow) threw 52 pitches over a three-inning simulated game Tuesday at Great American Ball Park, Gordon Wittenmyer of The Cincinnati Enquirer reports.

Greene came out of the session feeling great. While the successful sim game should set him up to return from the 15-day injured list to start Sunday against the Pirates, the team has not yet confirmed as much. If Greene does indeed start Sunday, he would be surely be working on a limited pitch count. The right-hander has been shelved since mid-August with right elbow inflammation.

Garrett (forearm) tossed three scoreless innings in his rehab start with Triple-A Jacksonville on Wednesday, striking out three batters while scattering three hits and two walks.

Garrett built up to 59 pitches (33 strikes) in the second start of his rehab assignment, after he previously tossed three scoreless innings for Single-A Jupiter on Sept. 5. Per MLB.com, Garrett is scheduled to make another rehab start Tuesday, and assuming he gets stretched out to around five innings and 80 pitches and experiences no physical setbacks, he could be cleared to return from the 60-day injured list thereafter. Garrett has been on the shelf since June 23 with a left forearm flexor strain.

Alcantara (elbow) threw live batting practice at LoanDepot Park on Tuesday, Christina De Nicola of MLB.com reports.

Alcantara faced batters for the first time since he underwent Tommy John surgery Oct. 6, 2023. The right-hander's rehab from the operation has moved along swimmingly thus far, and he should be ready to roll for the start of spring training.

Meyer registered a 5.18 ERA, 1.43 WHIP and 42:32 K:BB in 40 innings across 11 appearances for High-A Beloit.

Meyer was the consensus top prep righty in last year's draft, and it's an accomplishment for him to have logged 74 innings this season while climbing to High-A as a 19-year-old. However, his 16.3 percent walk rate at Single-A and 17.9 percent walk rate at High-A are dangerously high marks, even given his youth. He walked between two and five batters while never logging more than five innings over his last 10 starts. Meyer's got very strong stuff, but his control isn't ready for the upper levels.
