Purdue's thin margin of error along the offensive line may have gotten slightly thinner this morning when projected starting left tackle Martesse Patterson sustained a knee injury according to reports:
Potentially significant injury at #Purdue morning practice: starting LT Martesse Patterson, left knee. Unknown severity. Iced/walk w/ limp

this is a terrible blow for Purdue if he is out any sustained length of time. Patterson was a top reserve last season that even started three games. He was expected to hold down the left tackle spot on a line that does not have a ton of experience, especially at the tackle positions.
