Running back Knowshon Moreno has been activated by the Miami Dolphins after recovering from a left knee injury that forced him to miss the first 12 days of training camp.
Moreno came off the physically unable to perform list before Wednesday's practice and joined the competition for a starting job.
Moreno signed a $3.275 million, one-year contract in March after five seasons with the Denver Broncos. He helped them reach the Super Bowl last year when he had a breakout season, rushing for 1,038 yards, catching 60 passes and scoring 13 touchdowns.
Lamar Miller and Daniel Thomas were the primary ball carriers last season for the Dolphins, who ranked 26th in the NFL in rushing. Both remain on the roster, and Miller has looked good this summer with the first unit.
