Dallas Cowboys quarterback Tony Romo has revealed that he will undergo an MRI scan on his back after hurting it during yesterday's 24-23 win over the Washington Redskins.

Romo went into the match carrying a slight injury to his back, a problem that was exacerbated by a hit in the first half.

However, he stayed on the pitch and orchestrated the game-winning drive that resulted in a 10-yard touchdown pass to DeMarco Murray with 1:08 left on the clock.

The 33-year-old also suffered back problems last season and was forced to undergo surgery to remove a cyst in April, but he has revealed that his current troubles are not related to that injury.

"That [hit] triggered it a little bit. Whatever the kid did on that one play, it really sent something that didn't feel comfortable," Romo told reporters.

"But it's in a completely different spot than the back stuff I had last year, so that's a good sign. [I] played through it, just like anything in football."

The Cowboys' victory leaves them in the hunt for a playoff place, and they will win the NFC East if they beat the Philadelphia Eagles on Sunday - a match that Romo is expected to be fit for.
