Not sure as to the severity, but Molina does not strike you as one of the most physically resilient athlete in the bigs. As a result, Chad Moeller will most likely be called up with a corresponding adjustment to the 40 man roster in order to make room. Looks like the Girardi boot camp did little to correct last April's infusion of muscle injuries as Molina joins Derek Jeter and Jorge Posada as early victims to the injury bug.
The Star Ledger's assessment is a bit more optimisic:
With Derek Jeter close to being able to return to action at shortstop -- "He might be in there (Monday)," manager Joe Girardi said -- Alberto Gonzalez could be optioned back to Triple A. Or Molina could go on the disabled list.
"It's a little bit tight, that's all," said Molina, who hurt himself in Sunday's fourth inning on an awkward slide while scoring on a sacrifice fly. "Hopefully a couple days' rest, it should be all right."
