MANKATO — The Minnesota Vikings have placed cornerback Captain Munnerlyn, safety Andrew Sendejo and tight end Chase Ford on the physically unable to perform list to start training camp.

Ford is in a cast with a broken left foot and will be out indefinitely. Munnerlyn has a minor hamstring injury. Sendejo is dealing with nagging lower-back and ankle problems. Players on the PUP list during the preseason can be taken off at any time, and they count against the 90-man roster. They can’t practice until they’re medically cleared.

The Vikings also signed wide receivers Andy Cruse and Ty Walker on Friday and waived wide receiver Josh Cooper and offensive tackle Matt Hall. Cruse was on Houston’s practice squad last year and Walker spent time on both Green Bay’s and Seattle’s practice squads.
