Dolphins' Wilson to IR, will miss at least 4 games

Miami Dolphins running back Jeff Wilson Jr. will miss at least the first four games of the regular season after being placed on injured reserve Thursday.

Dolphins head coach Mike McDaniel said Wilson was placed on IR due to "a midsection injury compounded by a finger injury," according to Adam Beasley of Pro Football Network.

Raheem Mostert is in line to lead Miami's backfield in Wilson's absence, while De'Von Achane and Salvon Ahmed should act as the primary backups.

Wilson joined the Dolphins from the San Francisco 49ers in a midseason trade last year. He produced 392 yards and three touchdowns in eight games in Miami, and 468 yards and two scores in eight games in San Francisco.

Mostert led the AFC East club in rushing with 891 yards last season. Achane joined the Dolphins as a third-round pick in April and is dealing with a shoulder injury suffered in the preseason. Meanwhile, Ahmed has 532 yards across three seasons in Miami.
