Interim manager Chad Tracy didn't offer specifics, but the veteran first baseman likely underwent an X-ray. Contreras will have Monday's team off day to aid in his recovery ahead of Tuesday's series opener versus Philadelphia.

Harris, who turns 30 in June, made a big-league roster for the first time when he cracked the Nationals' Opening Day roster, but he hasn't impressed during his time with the team. In 18.1 innings, he's struck out nine batters and walked 12 while struggling to a 5.40 ERA and 1.80 WHIP. Chad Kuhl (foot) was activated from the injured list in a corresponding move.

The Red Sox were holding out hope that Anthony would be able to avoid a trip to the IL after he sprained his wrist during Monday's game, but the team didn't like the idea of playing with a short bench for another few days. The 21-year-old will be eligible to return to the lineup May 15. Until then, Masataka Yoshida figures to continue benefitting from additional starts at DH.

Casas' move to the 60-day IL frees up a spot on the 40-man roster for left-hander Eduardo Rivera, who was called up from Triple-A Worcester. The Red Sox placed Casas on the 10-day IL coming out of spring training while he was completing his recovery from knee surgery, and though his rehab from that injury has gone according to plan, the first baseman has since been shut down from activity after suffering a left abdominal strain earlier this month. Casas is without a clear timeline for a return, but Wednesday's transaction ensures that he'll be on the shelf through at least the final week of May.

Rodgers is slated to miss the entire 2026 season while recovering from right shoulder labral revision surgery, but the minor-league deal will allow him to conduct his rehab under the supervision of the Red Sox's medical staff. If healthy heading into next spring, Rodgers will likely be given the chance to compete for a spot on Boston's Opening Day roster, but he'll turn 30 in August and could struggle to earn another another opportunity in the majors. Even before his shoulder surgery, Rodgers endured a disappointing, injury plagued 2025 campaign with the Astros in which he slashed just .191/.266/.278 with a 35.9 percent strikeout rate over 128 plate appearances.

The move opens up a 40-man roster spot for new lefty reliever Danny Coulombe, who was signed to a one-year deal in a corresponding move. Gonzalez has been sidelined for the entirety of spring training due to left shoulder inflammation that could require surgery. With Gonzalez set to miss at least the first two months of the regular season, Kristian Campbell, Nate Eaton and Andruw Monasterio will be competing for at-bats and playing time.

It's unclear how long his neck has been bothering him, but Coulombe last pitched Friday. The lefty has yielded five runs with a 5:3 K:BB over eight innings out of the Boston bullpen this season. His spot on the roster and in the bullpen will be filled by Alec Gamboa.

It's the first time he's thrown a baseball since he underwent a UCL reconstruction and flexor tendon repair six months ago. Houck will continue a deliberate rehab process over the next several months and hopes to make a late-season return, but it's likely the Red Sox will hold him back until 2027.

While working his way back from the June 2024 internal brace surgery he required on his left elbow, Sandoval hit a setback in late April, when he was pulled off his rehab assignment after experiencing tightness in his left biceps. Though additional testing on his arm revealed nothing overly concerning, Sandoval has yet to restart his throwing program, making it unclear when he might be ready to resume his minor-league assignment. The move to the 60-day IL won't affect Sandoval's timeline for making his Red Sox debut, as he wasn't on track to be activated by late May following the recent setback.

The Red Sox plan to continue proceeding cautiously with Crochet while he works his way through left shoulder inflammation, but the club is optimistic that it caught the injury early enough and shut the lefty down before it became a greater concern. For his part, Crochet believes that he'll be ready to return from the IL when first eligible May 12, but the two-time All-Star still has a few more checkpoints to hit in the recovery process before the Red Sox pencil him back into the rotation.

Oviedo has been shut down over the past month after being diagnosed with a right flexor strain in early April. The Red Sox will determine the next steps for Oviedo's rehab based on what comes out of the upcoming exam with Dr. Meister.

Crawford had to be pulled off his rehab assignment when he developed soreness in his pitching arm during his first rehab outing. He has managed to avoid structural damage, however, and hopes to resume throwing "soon" after a brief shutdown period. Crawford hasn't pitched at the major-league level since 2024 because of injury.
