Dallas Cowboys quarterback, Tony Romo, re-injured his left collarbone in the team's game versus the Carolina Panthers on Thursday.

ESPN reported that the Cowboys star sustained the injury during the third quarter of the game when he was sacked by Panthers linebacker, Thomas Davis. The Panthers won 33-14.

The same report said that Davis fell on Romo during the sack and jammed the quarterback's shoulder. The injured player received initial treatment from the Cowboys' medical staff and then proceeded to the locker room for further tests.

He was seen walking from the field while holding his arm close to him.

Cowboys coach, Jason Garrett, said Romo's X-rays are still inconclusive and that he would need to undergo further medical examinations come Friday.

There is still no news on whether Romo will miss the remaining games of the season or when he is expected to return.

According to ESPN, Romo admitted that he felt the same sensation when he broke his collarbone earlier this season, causing him to miss seven games.

Last September, the quarterback first broke his left collarbone in the Cowboys' win versus the Philadelphia Eagles.

"I felt it. It has a little bit of a pop to it. Obviously I've felt it before. Your body kind of goes into a little bit of shock," the quarterback said in an earlier Yahoo Sports report.

With him re-injuring his collarbone, a lot of people are expecting that he may be given the entire season to rest.

In an update, ESPN's Ed Werder noted that Romo will miss the entire season since his recovered collarbone only lasted for two games. His source added that although the X-Rays were still inconclusive, it can be said that he is "done for the season."

Cowboys owner, Jerry Jones, told USA Today that the team still has a lot to learn from Romo.

"It's in the same shoulder that he was out five to six weeks for. That is a concern from the standpoint of the games ahead. We just need more information. We got an X-ray, but we need more than that. He certainly hurt his shoulder," Jones added.

During Thursday's match, Romo was not able to show his best performance, as he was only able to throw three interceptions, which included two returned touchdowns.

USA Today said this was the same thing that happened in their victory versus the Miami Dolphins, although the team managed to survive despite Romo's rusty performance.
