Post-game update: Good news out of Oakland. All tests came back negative and Tate traveled with the team back to Cincinnati, per Tom Pelissero.
UPDATE: It is not surprising Tate has officially been ruled out the rest of the game.
The Cincinnati Bengals have hung close with the Oakland Raiders, but they have lost wide receiver Auden Tate in the fourth quarter to an injury. Tate made a diving catch and took a hit to the head as he was going to the ground, per Pro Football Talk. He was subsequently placed on a stretcher and carted off the field. He was able to wave to the crowd as he went off the field.
He led the team with four receptions for 56 yards at the time of the injury.
