Irving, TX (SportsNetwork.com) - Dallas Cowboys coach Jason Garrett said quarterback Tony Romo will be day-to-day for practice this week because of his injured back.

The Cowboys also placed linebacker Justin Durant on injured reserve because of a torn biceps.

Romo suffered a back contusion during the third quarter of Monday's loss to Washington and sat out most of the fourth quarter before returning to the contest. He underwent a CT scan earlier this week.

"It's a day-by-day thing with Tony," said Garrett on Wednesday. "We'll see how he handles the pain and we'll see how functional he is as the week goes on."

Romo normally doesn't practice on Wednesday as part of his recovery from back surgery last year. He appeared somewhat limited during the final possession of regulation and overtime of Monday's 20-17 setback to the Redskins.

Durant was hurt in the second half on Monday. He was leading the team with 49 total tackles despite missing two games.

The Cowboys signed linebacker Tim Dobbins to fill the roster spot. Dobbins last played in the NFL during the 2013 season with Houston. He has also played for San Diego and Miami in an eight-year career, and has 253 total tackles.
