NFL: Jason Witten nixes report

Jason Witten chuckled when asked about a report that he had expressed interest in the head coaching job at the University of Tennessee and would walk away from the Dallas Cowboys to take over at his alma mater.

The 10-time Pro Bowl tight end said he’ll be on the field when the Cowboys play the Washington Redskins on Thursday night, and possibly for a few years to come.

“Coaching is something I can see myself down the road having one of those opportunities,” Witten said Monday. “But right now, I’m all in with this team.”

Witten has a relationship with Volunteers athletic director John Currie, who fired coach Butch Jones two weeks ago and then backed out of a deal with Greg Schiano, but Witten says he hasn’t talked with anyone at Tennessee lately.

Siemian back at QB

Trevor Siemian is the Denver Broncos’ quarterback again after Paxton Lynch’s 2017 debut ended with him in a walking boot and crying on the sideline.

Coach Vance Joseph said Lynch will miss two to four weeks with a high right ankle sprain he sustained in Sunday’s 21-14 loss at Oakland.

Nose tackle Domata Peko may miss a game for the first time since 2009. His 123-game streak is in jeopardy due to a sprained left medial collateral ligament that Joseph expects will sideline him a week or two. The Broncos also are waiting on MRI results on defensive end Derek Wolfe’s neck injury.

NFL suspensions

Broncos cornerback Aqib Talib and Raiders receiver Michael Crabtree both got two-game suspensions for their fight Sunday.
