Tony Romo Ruled Out For Season Reports ESPN But Cowboys' Jason Garrett Insists Treatment Is Plan

The Dallas Cowboys' playoff chances have likely taken a huge hit. They also may not have if you believe the team's coach.

A day after the Cowboys narrowly defeated the Washington Redskins 24-23 to set up a win-and-qualify matchup with the Philadelphia Eagles in Week 17, ESPN's Adam Schefter reported, citing an unnamed source, that quarterback Tony Romo had been ruled out for the remainder of the season with a back injury.

The 33-year-old quarterback admitted on Sunday that he "tweaked" his back during the thrilling win.

Also citing unnamed sources, ESPN's Chris Mortenson reported via Twitter on Monday that Romo would need surgery.

Speaking during a press conference on Monday, Cowboys coach Jason Garrett wouldn't even rule Romo out for this week let alone any possible playoff run.

“We have not made that determination at all at this point,” Garrett said, via the Cowboys' website. “Like with any player the day after a game, you just want to see what the injury is. We’ve done that with Tony. We wanted to get him involved in treatment as quickly as we can, and we started that process.”

Following Garrett's remarks, Ian Rapoport of also reported that Romo had been diagnosed with a herniated disk, also citing an unnamed source.

According to Rapoport's source, the team was holding out hope that Romo would be able to play in the season finale with the NFC East title on the line.

Citing an unidentified person familiar with the injury, Jarrett Bell and Jim Corbett of USA TODAY Sports also reported that Romo was done for the remainder of the Cowboys' season.

If Romo is unable to play then the Cowboys' playoff hopes will depend on the right arm of Kyle Orton.

“Right now, we have a quarterback who is getting treatment for an injury he had yesterday in the ball game,” Garrett added on Monday. “Kyle knows that he has to be ready. Kyle prepares like the starting quarterback each and every week.”
