Tamme left the game against the Cowboys on Sunday after suffering the injury. The league’s concussion protocol requires that Tamme return to baseline status of cognitive functions and be cleared by the team doctor and an independent neuropsychology consultant. At that point he can gradually return to practice and play.
Tamme has played 123 of 223 snaps this season (55 percent) and has eight catches for 104 yards. Levine Toilolo (139 snaps) is the only other tight end on the active roster. After Tamme left the Cowboys game, fullback Patrick DiMarco lined up at the tight end at times.
