Arlington, TX (SportsNetwork.com) - Dallas Cowboys quarterback Tony Romo received an epidural injection to relieve pain on the herniated disc in his back, according to a report by NFL.com.
The injection is a standard procedure in treating a herniated disc and the Cowboys hope to know by Wednesday or Thursday if the shot had a positive effect.
Cowboys coach Jason Garrett said Monday the team has "not made that determination at all" after reports surfaced on Monday saying Romo would miss the rest of the season with a back injury.
"We'll evaluate him on a day-by-day basis and make the best decision for our team," said Garrett.
ESPN.com reported that Romo needs surgery for a herniated disc and will miss the remainder of the season, including Sunday's winner-take-all showdown with the Philadelphia Eagles for the NFC East title and any potential games after that.
In addition, quarterbacks David Carr, John Skelton and Tyler Thigpen are working out for the Cowboys Tuesday as Dallas is seeking insurance behind backup Kyle Orton.
Romo led Dallas to a 24-23 victory over the Washington Redskins on Sunday, throwing a touchdown pass to DeMarco Murray with 1:08 remaining to keep the Cowboys' playoff hopes alive after they trailed by nine points in the fourth quarter.
Orton has started 69 NFL games, but none since 2011 while with the Kansas City Chiefs, where he landed after the Denver Broncos cut him in favor of Tim Tebow.
Orton, 31, has passed for 14,661 yards with 81 touchdowns and 57 interceptions in nine seasons.
"We have Kyle Orton here for a reason," added Garrett. "He understands what his role is."
