Rucci was claimed off waivers by the Lions on Monday, Tom Pelissero of NFL Network reports.
Rucci was cut loose by the Dolphins on Saturday, but he's quickly found a new home with the Lions. The 24-year-old will provide the team with some much-needed depth at tight end with Sam LaPorta (back) done for the regular season and Brock Wright (neck) potentially set for a prolonged absence. Rucci has failed to garner a target while playing 39 offensive snaps over four contests with Miami this year.
