The Miami Dolphins re-signed wide receiver Julius Pruitt and rookie wide receiver Keenan Davis, who was released by the Cleveland Browns on July 24.
Pruitt is entering his third season and made the 53-man roster with Miami in 2011 out of Ouchita Baptist, playing nine games on special teams. He was back with the Dolphins in training camp last summer but was released August 28 in the mandatory roster cutdown to the 75-player limit.
Davis was undrafted out of Iowa, where he played for current Miami wide receivers coach Ken O'Keefe. He caught 97 passes, including five touchdowns, for 1,284 yards in his final two seasons with the Hawkeyes.
They'll compete for roster spots created when Armon Binns tore multiple knee ligaments in Sunday's practice.
Binns and wide receiver Jasper Collins were waived/injured Wednesday. They're eligible to revert to the Dolphins' reserve/injured list if unclaimed.
