Running back Stevan Ridley was among three veterans placed on the physically unable to perform list by the New York Jets on Wednesday.
In addition, guard Willie Colon and defensive tackle Kevin Vickerson were also placed on the PUP list.
Ridley and Colon are recovering from knee injuries while Vickerson has a hamstring issue.
On a positive note, 2013 first-round pick Dee Milliner was not placed on PUP. Milliner was limited this offseason as he continued to recover from a torn Achilles suffered last October.
Players on PUP can be activated at any point during the preseason, but players must be placed on the list before the start of camp to be eligible to remain on the list during the regular season.
