Chiefs' Jamaal Charles off PUP list

ST. JOSEPH, Mo. -- Kansas City Chiefs running back Jamaal Charles has made his training camp debut.

Charles had been on the physically-unable-to-perform list the first three weeks of camp. He underwent surgery last season after tearing the ACL in his right knee in Week 5 against Chicago. He was at practice Tuesday.

Charles missed the Chiefs' preseason opener Saturday against the Seattle Seahawks, and it's not clear whether he will play against the Los Angeles Rams on Saturday.

The four-time Pro Bowl running back worked out a bit during the offseason program, and Charles said all along that he expected to be ready for the season opener against San Diego on Sept. 11.
