Kelce didn't return to the game and the Chiefs struggled offensively in the second half.
The Chiefs are taking a 21-3 lead into halftime of their wild-card playoff game against Tennessee after driving 79 yards in 1:52 and scoring on a 14-yard touchdown pass to Demarcus Robinson. The two-point conversion attempt failed - and almost brought disaster for the Titans when Mariota was sacked, but officials ruled he was down before the ball came loose. One play before former Chiefs kicker Ryan Succop connected from 49 yards, Mariota was sacked by inside linebacker Derrick Johnson, who appeared to force a fumble that was recovered by the Chiefs ... only to have the fumble overturned by Triplette - he ruled the ball dead due to forward progress, even though Mariota never appeared to move forward on the play.
The injury also puts his status in question for next week should the Chiefs advance. This score made the game a lot closer, at 21-10, with about half the third quarter left to play.
