LANDOVER, Md. -- Dallas Cowboys quarterback Tony Romo said he will undergo an MRI on his back on Monday, but he does not believe it will jeopardize his availability for next week's showdown against the Philadelphia Eagles.

Romo said his back, which was sore coming into Sunday's victory over the Washington Redskins, troubled him after a hit in the first half.

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

"But it's in a completely different spot than the back stuff I had last year, so that's a good sign."

Romo had surgery in April to remove a cyst from his back and did not take a snap until the team reached training camp in Oxnard, Calif., in July.

Romo was noticeably limping as he carried out play fakes on running plays. In the fourth quarter, he appeared to be in trouble even more after spinning free from the pocket on a third-down throw to Miles Austin. Romo appeared to kick the back of his leg as he escaped trouble, but he did not miss a snap.
