The Boston Red Sox placed Isiah Kiner-Falefa on the 10-day injured list with left forearm inflammation and recalled Anthony Seigler from Triple-A Worcester, according to MLB's official Red Sox transaction log.
The IL move is retroactive to June 21, giving Boston a fresh infield roster problem while moving Seigler back onto the major league roster as immediate depth.
Kiner-Falefa Goes On Red Sox IL
The official transaction wording is important because it stops at inflammation. It does not call the injury a fracture, does not provide a return timetable and does not say whether Kiner-Falefa will miss more than the minimum stay.
Over The Monster, citing Boston Globe reporting, said Kiner-Falefa underwent an MRI in Seattle and was expected to have a CT scan when the Red Sox returned to Boston. That adds concern around the injury without changing the official designation.
The timing also lands during a stretch of infield strain for Boston. The same Over The Monster roundup noted Romy Gonzalez had missed a rehab game with hip flexor soreness, so the Red Sox are not dealing with Kiner-Falefa's absence in isolation.
Seigler Recalled From Worcester
Seigler's recall is the corresponding move on the official log. MLB lists him as coming from Worcester, giving Boston another switch-hitting utility option while Kiner-Falefa is unavailable.
Earlier Red Sox coverage from Over The Monster described Seigler as a versatile player who has worked at catcher, second base and third base, with Triple-A production that made him a practical depth call when injuries opened space.
For now, the verified core is narrow: Kiner-Falefa is on the 10-day IL with left forearm inflammation, the move is backdated to June 21, and Seigler has been recalled from Worcester. Anything beyond that waits for the scan results or the next Red Sox update.
