MIAMI -- Defensive end William Hayes has signed a one-year contract to remain with the Miami Dolphins.
Hayes, acquired by Miami in a trade a year ago, played in 10 games as a backup in 2017 before being placed on injured reserve because of a back injury. He was the Dolphins' most effective run-stopping end.
Hayes is part of perhaps the deepest unit on the Dolphins' roster. Their other defensive ends include Cameron Wake, Andre Branch, Charles Harris and newly acquired Robert Quinn.
