The Dolphins also released wide receiver Mohamed Sanu, defensive back Quincy Wilson and offensive linemen Adam Pankey. Miami waived offensive lineman Blaise Andries, defensive linemen Niles Scott and Owen Carney Jr., running backs Gerrid Doaks and ZaQuandre White, and cornerback Elijah Hamilton.
Michel, 27, signed a one-year, $2.1 million with the Dolphins in May after spending a season with the Los Angeles Rams. He was critical for them down the stretch after taking over as the team's starter in Week 13; his 540 rushing yards from Week 13 through Week 18 were the third most in the NFL. He grew up in the Miami area, playing football at American Heritage School, roughly 20 miles from Hard Rock Stadium.
The former first-round draft pick of the New England Patriots is a two-time Super Bowl champion and has rushed for 3,137 yards and 18 touchdowns in four NFL seasons.
The team has until Tuesday at 4 p.m. ET to meet the 53-player limit. The Dolphins' roster stood at 67 after Monday's early moves.
