IRVING, Texas -- Left guard Ron Leary, who was sidelined with a groin injury last week, won't eliminate his chances to play Sunday against the Philadelphia Eagles at Lincoln Financial Field.

I think it'll be the same warm-up and see how it feels and hopefully they think I'm ready to go and then they give me the OK to go," Leary said.

Leary left the 27-26 win over the New York Giants. Guard Mackenzy Bernadeau replaced Leary and helped the Cowboys offensive line hold forth as quarterback Tony Romo led Dallas in his 26th fourth-quarter comeback to start 1-0.

The four-year veteran attributes his maturity as to why he exited the game rather than playing through the injury.

"The other day when I pulled, that's when I kind of felt it give out on me," said Leary. "I mean, I couldn't even run anymore. So, I knew I would be hurting the team by being out there. So, I came out."

Leary is familiar with the intricacies of groin injuries. Last year, Leary strained his groin against Washington in a 20-17 overtime loss. The next week, he missed the game, the only one of the season, against Arizona in a 28-17 loss.

"I think just because I've had it before I know what to do now coming off of everything quicker," Leary said. "I thinking coming out of the game when I did probably kept it from getting as bad as it was last year. So, you know, try to maintain it now."

On Sunday afternoon as the undrafted free agent out of Memphis in 2012 will demand to play Sunday if able.

"You always want to play."
