Tony Romo's season is over.

A CT scan Friday morning confirmed that the Dallas Cowboys quarterback suffered a hairline fracture in his left collarbone in the vicinity of a previous break. Surgery is not required, but for the third time in the past six years Romo is unable to finish a season because of injury.

Romo managed to start only four games, his lowest total since he became the franchise's starting quarterback during the 2006 season. The injury means Matt Cassel, who went 0-4 during Romo's initial absence this season, will start at quarterback.

Romo went down for the first time this season in Week 2, when a sack broke his left collarbone. Romo was injured again Thursday on the final play of the third quarter on a sack.

Redskins lose cornerback Culliver

•Washington cornerback Chris Culliver is heading to injured reserve after tearing ligaments in his right knee in practice Thursday. Coach Jay Gruden said Culliver tore his ACL and MCL. "Just a fluke deal," he said, adding that Culliver "went up for a ball, landed on [the knee] and it tore."

•Browns coach Mike Pettine said he hasn't decided whether Johnny Manziel, who was stripped of his starting job this week, will be active for Monday night's game against Baltimore. He was downgraded to third string after a video surfaced of him partying during Cleveland's bye week.

•Unless Case Keenum passes the NFL concussion protocol Saturday, St. Louis will turn to benched starter Nick Foles at quarterback Sunday. Coach Jeff Fisher verified that Keenum has not been cleared to play.

DeMarcus Ware's lower back injury will keep the sack specialist out of New England's Sunday-night showdown against the Denver Broncos.

•Cornerback Darrelle Revis will not play in the New York Jets' game against the Miami Dolphins because he is still dealing with a concussion.

•Buffalo Bills defensive tackle Kyle Williams will undergo surgery on his left knee and miss the rest of the season. He has been out since Week 6.


Shiffrin suffers heartbreak

Mikaela Shiffrin, just a few turns from winning a World Cup race at home for the first time, caught an edge and went down with the finish line in sight, giving Lara Gut of Switzerland a stunning giant slalom win in Aspen, Colo.

Gut completed the course in a two-run combined time of 2 minutes, 2.51 seconds, edging Austria's Eva-Maria Brem by 0.10 seconds. Federica Brignone of Italy took third.

This was a rough day for the U.S. Lindsey Vonn lost her left ski during the first run and slid into the netting.

Shiffrin was the first-run leader and was cruising toward a win. She said she began to think about what a victory on home snow might mean.

"You should never, ever think that because immediately something bad will happen," Shiffrin said."

Vonn called her own wipeout "super annoying."
