Miami re-signed Kroft on Thursday, Barry Jackson of the Miami Herald reports.
The Dolphins needed both Jalen Ramsey (knee) and Robert Jones (knee) to make it through their 53-man roster cut before placing them on injured reserve with the designation to return. As a result, they had to cut Kroft and subsequently re-sign him to the roster after the aforementioned players shifted to IR. The 30-year-old tight end is now set to backup Durham Smythe and Julian Hill at tight end, while also contributing on special teams.
