Pedro Leon Injury: Aggravates knee injury

Leon was pulled off his rehab assignment at Triple-A Sugar Land on Wednesday after aggravating his left knee sprain, Matt Kawahara of the Houston Chronicle reports.

Leon hadn't seen game action since Saturday and now the Astros have divulged the reason why. It's not clear at this point how long this might set Leon back. He's been out all season with a Grade 1 MCL sprain in his knee.
