Colts tight end Dwayne Allen can become a free agent after the 2015 season, but he said he's more concerned with how he performs than how much he'll earn in the future, reports the team's official website.

"I play this game because I want to be the best, not because I want to be the highest paid or anything like that," Allen said. "With the contract looming, it is what is. Me thinking about a contract isn't going to help me play any better on the field. Me focusing on having my body in the best shape possible to go out and help the team will."

Allen dealt with a high ankle sprain during the 2014 season, but he said he's healthy heading into the 2015 season.

"I felt 70 percent for the better part of [2014]," Allen said. "Having an offseason to really train like the offseason I had my rookie year or the offseason I had going into the second year, before I was injured, was my main focus. I'm glad I was able to get away and get that taken care of."
