ANDERSON, Ind. — The Indianapolis Colts will be without starting defensive end Kendall Langford for three to four weeks after having arthroscopic surgery on his injured knee.

Coach Chuck Pagano made the announcement when the team returned to Anderson University on Tuesday.

Pagano said Langford hurt his knee in practice last week, was sent back to Indianapolis for an MRI and doctors found a chondral defect. Pagano did not say which knee was injured, but Pagano remains hopeful that Langford will be ready for the Sept. 11 season opener against Detroit.

There was better news on rookie centre Ryan Kelly. Indy's first-round draft pick was expected to return to practice Tuesday afternoon after missing more than a week an injured left shoulder.
