The Miami Dolphins signed two wide receivers following Armon Binns' season-ending torn anterior cruciate and medial collateral ligament tears.
They signed Julius Pruitt for the second time after cutting him last year and Keenan Davis, an undrafted rookie from Iowa. Pruitt played in nine games for Miami two seasons ago.
Wide receiver Jasper Collins was waived-injured.
The Dolphins tried out wide receiver Laurent Robinson, but he has a history of concussions that includes four last season with the Jacksonville Jaguars.
