SMU standout tight end RJ Maryland is done for the season after sustaining a torn ACL in his right knee during last weekend’s 40-10 rout of Stanford.Maryland was injured in the third quarter when he took a hit from Stanford cornerback Collin Wright after catching a short pass in the left flat.Mustangs coach Rhett Lashlee termed the blow as a “violent hit.””RJ is going to be out for the year,” Lashlee told reporters Tuesday. “Got the news we expected yesterday, so probably will have more detail on that in the coming weeks, but he’s gonna have to have surgery and he’ll be out for the rest of the season. Yes (it’s an ACL), but there are some other things, so just kind of waiting on the specifics, but yes, that is part of it.”Maryland is the team’s top target. He leads the No. 22 Mustangs with 24 receptions, 359 yards and four touchdowns.
