WHITE SULPHUR SPRINGS, W.Va -- The New Orleans Saints have waived defensive end Glenn Foster with a failed physical designation and signed defensive back Travis Manning.

Foster, a 2013 undrafted rookie out of Illinois, went on IR last October after sustaining a knee injury against the Lions. He has been unable to practice all summer while rehabbing and was on the physically unable to perform list as of Thursday.

Foster has spent most of the offseason practices working off to the side with an athletic trainer while wearing a knee brace.

Manning, an undrafted rookie free agent out of Northwest Missouri State, was briefly with the Packers in May and also participated in the Chiefs minicamp on a tryout basis.

Manning, 5'11, 196 pounds, was one of three cornerbacks, including Alfonzo Dennard, who tried out on Thursday with P.J. Williams, Keenan Lewis and Damian Swann out of commission. He and current Saints cornerback Brian Dixon were former teammates.
