Mike Vrabel has turned down an offer to become the San Francisco 49ers' defensive coordinator.

Vrabel has been linebackers coach of the Houston Texans over the past two seasons.

Bill O'Brien and general manager Rick Smith worked hard behind the scenes to keep Vrabel and will give him a new contract, the Houston Chronicle reported, citing sources.

Vrabel met with new 49ers coach Chip Kelly on Tuesday before declining the job, the Chronicle reported.

J.J. Watt underwent surgery for a sports hernia.

Watt again was one of the best defensive players in the NFL in 2015.

Jadeveon Clowney stormed out of the Houston Texans' locker room and left the stadium after he was ruled out of their Wild Card game against the Kansas City Chiefs.

The Texans listed Clowney among their inactives following a pregame workout in the weight room. Clowney was upset about the decision, believing he was ready to play.

The team acknowledged that Clowney had left the stadium but said he would return before kickoff.

Clowney is recovering from a significant foot injury he suffered two weeks ago.
