Kroft, who has 105 receptions over seven NFL season, will join a crowded Miami tight end room alongside Durham Smythe, Tanner Conner, and Eric Saubert, and others. Once an analytics darling, Kroft, 30, served as a depth player in San Francisco last season. He has little chance of fantasy relevance with the Dolphins. 

Kroft has been sidelined since suffering an MCL sprain back in Week 2. This limited practice puts him on track to return Sunday against the Falcons. He will not be a fantasy option in that matchup. 

With George Kittle (groin) out Week 2 and Kroft injured midway through the game, Charlie Woerner and Ross Dwelley handled tight end duties. The good news for San Francisco is it sounds like Kittle is inching closer to a return, possibly making his season debut in Week 3.

Kroft drew the start for San Francisco with George Kittle sidelined in Week 2. He was not targeted before going down in the third quarter. Ross Dwelley is the next man up at tight end.
