Dallas Cowboys star quarterback Tony Romo is injured once again and now could be out for the entire season. Romo suffered his second collarbone injury this season in Dallas' 33-14 loss to the undefeated Carolina Panthers on Thursday (Friday in Australia).

The 35-year-old Romo had X-rays taken on the collarbone after the game but the results were inconclusive, according to reports. A follow-up check-up on the collarbone is expected later this week and could decide the status of Romo.

However, ESPN’s Ed Werder is stating, mentioning a “source close to the situation”, that the Cowboys QB will be out for the rest of the year.

"There are so many subtle things that come up when you see different things and you just have to get there," a disappointed Romo said postgame via ESPN.

"I wasn't quite there yet. It was going to take a little bit of time. You hope you can win games until you get that back, but it's just disappointing I wasn't able to do that and played poor today. I really put our team in a hole. That was the difference in the ballgame, really."

Romo, who had 3 interceptions against the Panthers, has played in just four games in the 2015 regular season injuring his collarbone in the game against the Philadelphia Eagles last September. He sat out Week 3 to Week 9 and returned to action last week in a win against the Miami Dolphins.

The Cowboys dropped to 3-8 for the season and a playoff appearance is looking bleak, especially with the latest injury to Romo.
