Moustakas exited Wednesday's game against the Tigers due to right knee irritation, Rustin Dodd of The Kansas City Star reports.
Moustakas was 2-for-3 before Ramon Torres took over for him in the seventh inning. He missed a few games at the end of August with a knee issue, but it's unclear if the two are related at this point. The good news is the Royals deemed the exit precautionary, so Moustakas may not have to miss much, if any, time due to the ailment. He'll be considered day-to-day for now; more should be known about his status once he is reevaluated Thursday.
