Manager Brad Ausmus indicated after Wednesday's game that Cabrera is hobbled by a "contusion" and has "got some fluid in his knee, so it's going to be sore sometimes," Matthew B. Mowery of the Oakland Press reports.
Cabrera's injury doesn't appear to be anything serious and he played the entire game (rain shortened it to five innings). Given the Tigers' current battle for a playoff spot, it would likely require a lot for the veteran slugger to miss a contest. Regardless, it may be something worth monitoring ahead of Thursday's series finale against the Indians.
