Dallas Cowboys quarterback Tony Romo has two fractures in his back but could still play Sunday against the visiting Arizona Cardinals, according to ESPNDallas.com.

Romo was injured during Monday night’s loss to the Washington Redskins, but returned to the game. The Cowboys said during the week that Romo only had a contusion.

However, ESPN attributed its report to multiple sources.

The team and Romo have said his latest back injury is not related to the disk surgery he had last December and is not a season-ending injury.

Baylor quarterback Bryce Petty sustained a similar injury this season and missed only one game.

Specifically, Romo reportedly has two fractured transverse process, which is a small bone that sticks out from either side of the vertebrae. Romo has been receiving several hours of treatment throughout the week at home and at the team’s facility.

Romo took a knee to the back from Redskins linebacker Keenan Robinson during a sack in the third quarter. X-rays were negative and he returned to the game after receiving a pain-killing injection. He then had a CT scan on Tuesday.

The Cowboys said Friday that Romo’s playing status is a game-time decision. Brandon Weeden would start at quarterback if Romo cannot play, with undrafted free agent Dustin Vaughan as the backup. Weeden replaced Romo while he was out against the Redskins.

The Cowboys leave for London on Monday for their Nov. 9 game against the Jacksonville Jaguars.

Romo missed three games in 2008 with a broken pinky finger, 10 games in 2010 and the 2013 season finale after having back surgery.
