Dallas Cowboys linebacker Rolando McClain has revealed that he is not concerned that he and the club have not held discussions over a new contract.

The 25-year-old joined the Cowboys in the off-season in a trade deal from the Baltimore Ravens, after initially announcing his retirement from the NFL in 2013 and again earlier this year.

However, McClain has found a new lease of life with Jason Garrett's side, and his performances have led to talk over him extending his stay with the club beyond the 2014 season.

"We haven't talked about it and I'm not worried about it," McClain told reporters. "I'm getting ready for the Giants.

"I'm just happy to be with the Dallas Cowboys. I'm happy with our success so far. I'm having fun with my teammates. Having a good time, gelling together and playing some good ball right now."

McClain has recorded 27 tackles, one sack and two interceptions this season.
