FOXBOROUGH, Mass. (AP) — Miami Dolphins running back De’Von Achane left Sunday’s game against the New England Patriots with a concussion.

It took a long time for Achene to get up after a helmet-to-helmet hit by Jaylinn Hawkins along the sideline after a 12-yard gain in the first quarter. The team later confirmed a concussion and said he would not return.

After averaging 7.8 yards per carry as a rookie last season, Achane has just 165 yards on 53 carries this season, an average of 3.1 yards.

The concussion diagnosis is especially troubling for Miami, where quarterback Tua Tagovailoa has been sidelined repeatedly with brain injuries.
