BALTIMORE -- Tennessee Titans tight end Delanie Walker was knocked out of Sunday's game against the Baltimore Ravens with a concussion after absorbing a big hit from safety Terrence Brooks.

Walker was initially credited with a 12-yard catch on the second-quarter play. Baltimore challenged the play and the call was overturned into an incomplete pass.

Walker took to Twitter after being ruled out for the game, tweeting that he's "all good."

I'm all good i just like to thank the fans for checking up on me, sometime you give them and sometimes u get them and i just got mines lol.. — Delanie walker (@delaniewalker82) November 9, 2014

Running back Leon Washington was flagged for unsportsmanlike conduct after the hit, and his head-butting of a Raven resulted in a loss of 15 yards for Tennessee.

Walker had three catches for 37 yards. He came into the game as the team's leading receiver with 475 yards and was tied for the team lead with four touchdowns.

The Ravens defeated the Titans, 21-7.
