UPDATE: Nwaneri returned to the lineup with 8:53 remaining in the second quarter.
NASHVILLE -- The Jags came into this game with offensive line questions and now their depth is already being tested.
Nwaneri was then helped off the field with a left knee injury and has been replaced by Tutan Reyes.
It was just announced in the press box that both are questionable to return.
The team is down to five healthy offensive linemen.
