Denver Broncos quarterback Peyton Manning has admitted that at this stage in his career he is only focusing on one game at a time.

The Broncos take on the New England Patriots in Sunday's AFC championship playoff game, and Manning said that with any injury likely to affect him more now than earlier in his career he is just enjoying playing while he can.

"As a matter of fact, I think it's probably even easier just to hone on in on what's taking place right now," he told the club's official website. "I really felt that that has been my approach since the beginning of last season.

"Just when you go through a significant injury and a major career change, you truly do go one year at a time and you don't look past what's going on now because you are not sure what's going to happen. Tomorrow is not promised. I think it's a healthy approach for an older player to go all in for 2013 regular season, 2014 post-season."

Manning threw for a career-high 5,477 yards in 2013.
