According to Chris Peak of Panther Lair, Jaryd Jones-Smith suffered a knee injury and is out for the 2015 season. He will have surgery this week. Jones-Smith was set to start at RT this upcoming season. Unfortunately Jones-Smith has already used his redshirt, so he will lose a season of eligibility. Peak had this say about who could replace him:
The most likely option might be to move redshirt freshman Alex Bookser, who worked at right guard in spring camp but came to Pitt as a highly-regarded offensive tackle prospect. That scenario would probably mean a move for redshirt sophomore Alex Officer from center to right guard and a return to the starting lineup at center for redshirt senior Artie Rowell.
