Leasure will miss the remainder of this season and likely all of next season while on the mend. Fegan notes that the right-hander hopes to be ready for spring of 2028. Leasure landed on the injured list in late May with a right flexor strain, and while he had been cleared to resume throwing side sessions at the beginning of August, it was ultimately determined that he needed to go under the knife to repair his UCL.

Leasure underwent surgery to repair a torn UCL in August, James Fegan of the Chicago Sun-Times reports.
Leasure will miss the remainder of this season and likely all of next season while on the mend. Fegan notes that the right-hander hopes to be ready for spring of 2028. Leasure landed on the injured list in late May with a right flexor strain, and while he had been cleared to resume throwing side sessions at the beginning of August, it was ultimately determined that he needed to go under the knife to repair his UCL.

Leasure (forearm) has resumed throwing bullpen sessions, MLB.com reports.
Leasure has been sidelined since late May with a right flexor strain. He was able to resume bullpen sessions in late July, and he is expected to return at some point in August. However, he will almost certainly need a rehab assignment, so he may not be activated until late in the month.

The White Sox transferred Leasure (forearm) to the 60-day injured list Saturday.
Leasure landed on the injured list Friday with a right flexor strain and will be shut down from throwing for four weeks. He isn't expected to be activated until the second half of the season, so the White Sox will stash him away on the 60-day IL and give his 40-man spot to Jacob Gonzalez, who joined the big club Saturday.

Leasure (forearm) said Friday that he will be shut down from throwing for four weeks, James Fegan of SoxMachine.com reports.
Leasure said his UCL is intact, but he's dealing with a lot of inflammation and has been diagnosed with a right flexor strain. Leasure was placed on the 15-day injured list Friday but is looking at an extended absence into July.

The White Sox placed Leasure on the 15-day injured list Friday with a right flexor strain.
Leasure allowed one run on one hit in one inning of work in Thursday's 6-2 win over the Twins and will now miss at least the next couple weeks after posting a 6.27 ERA, 1.23 WHIP and 18:8 K:BB across 18.2 innings this season. Lefty Tyler Gilbert was recalled from Triple-A Charlotte in a corresponding move.
