The Miami Dolphins made a series of roster moves early Wednesday, signing receivers Julius Pruitt and Keenan Davis while waiving/injured Armon Binns and Jasper Collins.
Binns' release was expected; he tore his ACL and MCL during practice Sunday. The nature of Collins' injury was unclear.
Pruitt returns to the team where he spent parts of two seasons. Davis is a rookie out of Iowa, where he caught 112 passes for 1,470 yards and seven touchdowns in his four-year career. With the Hawkeyes, he played under offensive coordinator Ken O'Keefe, who is now the Dolphins' receivers coach.
