Dolphins signed undrafted free agent RB Gerald Riggs Jr.
Riggs has upside for fantasy leaguers with Ricky Williams out for next season. He’ll push incumbents Travis Minor and Sammy Morris to be the ‘Fins top backup behind Ronnie Brown. The son of the former Redskins goal-line stalwart, Riggs Jr. suffered an injury his senior season at Tennessee and was projected before the draft as a middle to late-round pick.
