Jurickson Profar was pulled in the sixth inning of last night's game between the Round Rock Express and the Las Vegas Area 51s in the middle of an at bat.

According to folks on Twitter, Profar was pulled after apparently injuring his left hand or wrist after fouling a ball off.

There's no indication at this time what exactly the injury is, the extent of the injury, or how much time (if any) Profar may miss.

Profar spent time on the disabled list in 2011 with a left wrist injury, but hasn't had any significant health issues since then.

Profar came into the 2013 season as the consensus #1 minor league prospect in baseball, and is thought by many to be major league ready at the age of 20. Profar has been playing both shortstop and second base in AAA Round Rock this season, and has a .223/.333/.369 line for the season.

UPDATE -- Per Drew Davison on Twitter, Profar hyperextended his left thumb on a swing last night, but the numbness went away and he "should be good to go."
