Mike Boone: Everything you need to know

Boone rushed the ball seven times for 27 yards and a touchdown in Saturday's 14-6 preseason win over the Jaguars. He added one catch on two targets for eight yards. Both De'Von Achane (calf) and Jaylen Wright (leg) were unavailable, which left Boone as the second back to enter the game for Miami. He played a significant role in Miami's scoring drive to begin the third quarter, converting a first down with a six-yard run and then finding the end zone on a seven-yard scamper. Though Boone just joined the team two weeks ago, he looks to have a decent chance to make the roster as a depth option.

The Dolphins signed Boone to a contract Monday. With Alexander Mattison (neck) being placed on injured reserve, the Dolphins bolstered their backfield Monday by adding Boone and Aaron Shampklin. Boone appeared in six regular-season games for the Panthers in 2024 and posted 13 carries for 51 yards along with one catch (on three targets) for minus-2 yards. Boone, Shampklin and Ollie Gordon will compete for the RB3 job behind De'Von Achane and Jaylen Wright.

Boone rushed four times for 18 yards and caught his only target for minus-2 yards in Sunday's 44-38 overtime win over the Falcons. The 29-year-old shared the Panthers' top backup running back duties with Raheem Blackshear, playing behind Miles Sanders, who returned from an ankle injury in the Week 18 win. However, Boone was outproduced by both Sanders and Blackshear, as they averaged 5.8 and 11.8 yards per touch, respectively, compared to Boone's 3.2. The veteran back finished his 2024 campaign with 51 rushing yards on 13 carries, appearing in just six games.
