The Philadelphia Eagles have interest in tying starting quarterback Sam Bradford to the franchise beyond the upcoming season and have begun discussing a contract extension, according to sources.

It is not expected the negotiations would result in a long-term contract but more likely an agreement providing the team control of Bradford past the 2015 season, the final year of his current contract.

Despite the concerns about Bradford's injury history, Kelly recognizes the potential for Bradford -- taken No. 1 overall by the St. Louis Rams in 2010 -- to be a franchise quarterback.

"Peyton Manning switched teams because of an injury,'' Kelly said of Manning, who moved from the Indianapolis Colts to the Denver Broncos after a year off following neck surgery. "Drew Brees switched teams because of an injury. So we went down that path."

The Eagles acquired Bradford in a trade that sent Philadelphia starting quarterback Nick Foles to the Rams. Bradford has one year left on his original NFL contract and is scheduled to make $12.95 million this season.
