Tonyan has not played this preseason and hasn't returned to practice after being sidelined July 31 with back spasms, the St. Paul Pioneer Press reports.
Tonyan had a shot to be a sleeper in the offense with T.J. Hockenson likely to miss games as he works his way back from an ACL injury. However, he's going to have a hard time making the roster with the injury and could end up being released or placed on injured reserve.
