Sinkfield, a 6'1", 196 pounder out of Northern Iowa, has spent time with the Dolphins, Packers and Bills this season.
From the Giants:
The Giants’ wide receiver corps has been depleted. Victor Cruz is sidelined with a heel contusion and Ramses Barden with a sore knee. Louis Murphy missed practice yesterday with leg soreness. Kris Adams and Keith Carlos were both waived/injured. Jeremy Horne was injured and waived earlier in camp. The Giants recently added receivers Julian Talley and Marcus Harris.Sinkfield appears to here for the short term as first cuts are due next Tuesday, when teams are required to trim their rosters from 90 to 75 players.
