Of all the ways we've seen careers end on the field, it's hard to believe that a freak golf-cart accident may claim one off it.

Matt McChesney, a 28-year old guard/center for the Broncos, is expected to retire after the same ankle he had surgically repaired after a preseason injury last year was ran over by a golf cart. Just as McChesney got out of his cart to approach his ball, the trailing cart clipped his ankle.

"It was a freak accident," said McChesney, who played in three games as a defensive tackle/special teamer for the Jets in 2005 and was on their practice squad in 2006 before a brief stint with the Dolphins, to the Denver Post's Mike Klis. "It stinks."

McChesney's accident comes just a few weeks after Denver's All-Pro offensive tackle Ryan Clady suffered a partially torn patellar tendon his left knee while playing basketball. He is expected to miss most of training camp and the preseason.

As a result, the Broncos have told McChesney to try and rehabilitate the injury and compete for a job — possibly as a starter — in training camp. But the Colorado alum, who was the Buffaloes' defensive player of the year in 2004, appears ready to hang it up, especially after numerous injuries.

"It's been a long road," he said.
