WHAT TO WATCH FOR

Here are a few more story lines to watch:

DEEP THREAT

The Chiefs lost kick returner AkeemHunt to an injury last weekend against Denver, and special teams coach Dave Toub said Hill could return against the Titans. The speedster was taken off that particular duty this season to keep him fresher for the offense. Toubwas askedwhat the Chiefs lost in that sacrifice. “Maybe two touchdowns,” he said flatly.

SPECIAL TEAMS

The Titans beat the Chiefs 19- 17 in December 2016on a gameending field goal by Ryan Succop, who had spentmost of his career with Kansas City. Succop came up short on his first attempt at the 53- yarder, but Chiefs coach Andy Reid had called timeout just before to give him another shot. Succop made the mulligan for a victory in the coldest game in franchise history.

MARIOTA’S MOMENT

Young QBMarcus Mariota struggled down the stretch, when the Titans lost three straight. But while his numbers against Jacksonville last week to help clinch a postseason berth weremodest, several teammates said Mariota got his swagger back. “It was just me being me,” he said. “Again, I’m going to do whatever it takes to win. This is the time in the season when you’ve just got to lay it all on the line.”

WATCH FOR FLAGS

The Chiefs were among the most penalized teams in the NFL, getting flagged 118teams. The Titans were the secondbest in the league, drawing just 85penalties — second- fewest in franchise history for a 16game season. In a playoff game with razor- thin margins, penalties could be the difference between winning and losing.

ARROWHEAD MYSTIQUE

The weather should be in the 40s for kickoff, or about 40 degrees warmer than when these teams met last season. “There’s nothing like Arrowhead Stadium when that place is packed,” Reid said, “and it’s a little cold and the ground is shaking a little bit. It doesn’t get any better.”
