Kelly injured his right hamstring during training camp practice July 25 and has since been complaining of soreness in both knees. He returned last week to take part in some drills but was obviously laboring while on the field. He sat out Sunday's Hall of Fame Game against the Indianapolis Colts.
"It has been kind of stiff. ... We just thought we'd do things as soon as we can if there is a problem," coach Jim Zorn said.
Kelly was a second-round pick from Oklahoma in this year's draft. He and fellow rookie Devin Thomas were expected to contend for the No. 3 receiving spot, but both have been hurt for much of camp.
Thomas missed Sunday's game with a hamstring injury and also isn't expected to play in Saturday's game against the Buffalo Bills.
