It took only a few minutes after being carted off the field in the second quarter against the Ravens for Titans tight end Delanie Walker's day to end.
Walker has been diagnosed with a concussion after being leveled by Ravens safety Terrance Brooks on a third-and-7 pass attempt from Zach Mettenberger.

The play occured with 2:22 left in the first half and the game tied at 7. Within minutes of being carted off the field, before the half was even over, the Titans ruled Walker's day over with the concussion.
This is the second recorded concussion of Walker's career. In 2013, Walker was knocked out of the Titans' Week 13 game against the Colts and sat out the following week.
Walker, a nine-year veteran, led the team in receiving with three catches for 37 yards before leaving the game. On the season, Walker has 38 catches for 512 yards.
