Latest news
Flaherty (forearm) was reinstated from the 15-day injured list Sunday and struck out one batter while allowing one hit and no walks over two scoreless innings in the Tigers' 4-2 loss to the Pirates in the season finale.
Flaherty, who had been on the shelf since July 21 due to right flexor inflammation, made a pair of rehab appearances with Triple-A Toledo before being cleared to rejoin the Tigers ahead of the season finale. Since he wasn't fully stretched out for a starting role, Flaherty ended up making his first appearance out of the bullpen since the 2023 campaign. The 30-year-old righty is scheduled for unrestricted free agency this winter.

Flaherty (forearm) will be activated from the 15-day injured list and pitch during this weekend's series against the Pirates, Cody Stavenhagen of The Athletic reports.
He could follow either Justin Verlander (hamstring/hip) on Saturday or River Ryan on Sunday in a piggyback role, as neither Verlander nor Ryan are stretched out to handle a full workload. Flaherty's stamina isn't built up, either, but he was scheduled for a 2-to-3-inning simulated game this past Saturday. The right-handed hurler has been sidelined since late July due to right forearm flexor inflammation.

Flaherty (forearm) is slated to throw a 2-to-3-inning simulated game Saturday, Jason Beck of MLB.com reports.
Flaherty made a rehab start last Sunday with Triple-A Toledo, throwing 19 pitches over 1.1 scoreless innings. He will get stretched out a bit more Saturday and could rejoin the Tigers rotation next week, though he likely wouldn't be prepared for a full workload. Flaherty has been shelved since late July due to right forearm flexor inflammation.

Flaherty (forearm) began a rehab assignment with Triple-A Toledo on Sunday, striking out two while yielding one hit and one walk over 1.1 scoreless innings.
Making his first appearance in seven weeks, Flaherty threw only 19 pitches in the outing, so he's not close to being fully stretched out. The veteran right-hander has been sidelined since late July due to right forearm flexor inflammation.

Tigers manager A.J. Hinch said Friday that Flaherty (forearm) could begin a rehab assignment with Triple-A Toledo this weekend, Chris McCosky of The Detroit News reports.
Flaherty has progressed well of late as he ramps up his throwing progression, and he could test things out in a game setting soon. The veteran right-hander has been sidelined since late July with right forearm flexor inflammation. Flaherty could need a couple rehab appearances before rejoining the Tigers' rotation later this month.

Flaherty (forearm) threw a bullpen session Sunday in Kansas City, MLB.com reports.
The Tigers reportedly came away encouraged by how Flaherty looked during his first time getting back on a mound since he landed on the injured list July 21 due to right forearm flexor inflammation. Flaherty is expected to throw another side session within the next few days before he potentially moves on to facing hitters in live batting practice.
