Russell Wilson had his jaw realigned following the hit he took in last Thursday's game by Karlos Dansby.
Wilson said he feels fortunate to have avoided suffering a fracture.
"It was pretty close," he said Friday. "The doctor was like, 'Man, any harder, we probably [would have] had to wire your mouth shut,' so that was a good thing that didn't happen."
Dansby was fined $18,231 by the NFL.
Wilson was sent off the field by referee Walt Anderson to be evaluated for a possible concussion then returned after missing one play without being examined, which led the NFL to launch an investigation into whether the team followed proper protocol.
