Casas suffered a left patellar tendon rupture on Friday night and is facing a lengthy absence. Historically speaking, it’s one of the more challenging injuries to make it back from, with recovery times typically in the six-month range. There should be an update on his long-term prognosis at some point in the coming days. Fantasy managers shouldn’t expect him back until the outset of the 2026 campaign.

Casas suffered what Red Sox manager Alex Cora called a “significant injury” to his left knee on Friday night when he stumbled across the first-base bag while beating out an infield chopper. The 25-year-old first baseman is undergoing treatment at a local hospital. Fantasy managers should anticipate a lengthy absence since he’ll likely wind up requiring a significant surgical procedure.

Casas injured his left knee while running to first base during the second inning of Friday’s contest against the Twins and had to be carted off the field. It sounds like the 25-year-old slugger could be looking at an extended stay on the injured list. Expect the Red Sox to provide another update on his status, and probably make a couple of roster moves, prior to Saturday’s ballgame.

Casas tripped over the bag at first base and went down in a heap, clutching at his left knee while on the ground. He’ll head for further evaluation to see exactly what’s going on there. Look for the Red Sox to provide an update on his status as soon as more information becomes available.
