Titans running back Chris Johnson was hit in a helmet-to-helmet tackle near the sideline from Philadelphia linebacker Ernie Sims in the first half.
The NFL has cracked down on helmet-to-helmet hits, fining three players $175,000 last week and threatening suspensions for such hits in the future.
Sims was not penalized for the hit, bu the drew plenty of boos from the crowd when it was replayed on the Jumbrotron.
Afterward, Titans coach Jeff Fisher said he would have to see the play on film before deciding if it was an illegal hit.
“The rule is if the ball carrier is defenseless, if he's on the ground, it's a foul … I'd have to look at the play, but that's how it's set up,” Fisher said.
Asked about the hit, Johnson made it out to be no big deal.
“There's nothing I pay too much attention to. If the ref calls it, then he does. I'm not really worried about it,” Johnson said.
Johnson and the Titans had a visit from a former teammate as LenDale White was in attendance at the game.
White, who is on injured reserve with the Denver Broncos, was wearing a boot on his right foot because of surgery for a torn Achilles tendon. He said he is scheduled to have the boot removed next month.
White was traded to Seattle on draft day, but was released by the Seahawks in the offseason and eventually signed with the Broncos.
