IRVING, Texas (AP) -Dallas Cowboys receiver Terry Glenn had arthroscopic surgery on his right knee for the second time in six weeks Thursday.
Glenn reinjured his knee last week when he tried to return to practice for the first time since the initial surgery Aug. 1 to remove a cyst. That was a week into training camp.
``This gives Terry a chance to play this season,'' Cowboys spokesman Rich Dalrymple said. ``He will do everything he can to get on the field this year.''
Still, the team said there is no timetable for Glenn's return.
The latest operation was done in Columbus, Ohio, by Dr. Christopher Kaeding, the orthopedic surgeon for Ohio State, Glenn's alma mater. Kaeding removed loose cartilage from the knee.
Dalrymple said Glenn, the 33-year-old receiver in his 12th NFL season, may still need a more extensive microfracture procedure in the future.
Glenn is coming off consecutive 1,000-yard receiving seasons with the Cowboys, his third NFL team. He also played for New England (1996-2001) and Green Bay (2002).
