Peyton Manning quashed off rumors suggesting that he will consider retirement after their upcoming showdown with the Seattle Seahawks at Super Bowl XLVIII at the MetLife Stadium in New Jersey.

Manning, who is playing in his second season with the Broncos, eased the concern of their fans after the famous quarterback confirmed that he is not going anywhere next season regardless of their upcoming Super Bowl Sunday showdown with the Seahawks.

The 37-year-old quarterback admitted that walking away from the game as champion like what John Elway and Ray Lewis did last year, but Manning insisted that he will continue playing as long he is still enjoying the game. He revealed that both Elway and Lewis told him that their retirement was influenced by their physical condition.

"I think when you still enjoy the preparation, the work part of it, I think you ought to be still doing that," Manning said via The Denver Post. "When I stop enjoying it, when I can't produce, when I can't help the team, that's when I'll stop playing. If that's next year, maybe it is. I certainly want to continue to keep playing."

Manning is still obviously enjoying as proven by his numbers this season, throwing for 55 touchdowns and 5,477 yards during the regular season.

In their victories over the San Diego Chargers and the New England Patriots in this year's NFL Playoffs, Manning had a combined four touchdown throws and 630 passing yards, showing that he still has a lot of gas left in his tank.

Meanwhile, in other NFL news, the San Francisco 49ers are expected to make moves in the offseason after failing to reach this year's big dance.

The 49ers showed tremendous improvement on their cornerback position, but one of their players could find his way out soon as reports suggested that Tarrell Brown could walk away via free agency.

But Bill Williamson of ESPN noted that while Brown is expected to get attention, the 29-year-old CB could opt to stay with the 49ers, but he would need to accept a team-friendly deal for that to happen.

San Francisco recently inked fellow CB Tramaine Brock to a four-year deal worth $16 million earlier in the season - a deal which could affect the team's approach to the impending free agency of Brown.

"I could see Brown exploring the open market, but I can also see him coming back. Last year, there were several cornerbacks that got less than what they expected in free agency. If the market is the same this year -- there is no reason to think it won't be -- the 49ers might be able to bring the solid player back at a team-friendly deal," Williamson noted.
