Brett Keisel: 'I could play for two more years'

Pittsburgh Steelers defensive end Brett Keisel believes that he still has the ability to play for two more seasons.

The 35-year-old admitted earlier in the season that he could be close to end of his career after 11 years in the NFL with the Steelers.

"I think I've got a couple [years] left in me," Keisel told ESPN. "I feel great and still feel like I can play. We'll see what happens."

Keisel had 29 tackles and four sacks in the 2013 season.
