Kyle McCord will start at quarterback for Miami as Willis heads to IR for at least four games.
The Dolphins placed quarterback Malik Willis on injured reserve Tuesday afternoon, a move that will sideline him a minimum of four games with a worsening groin injury.
Willis had been getting treatment on the injury for the past two weeks. He ran less than usual against the New England Patriots on Nov. 1, managing one attempt for 2 yards, but downplayed how much it was affecting him. That changed after Sunday's 19-9 loss to the Detroit Lions, where he was visibly hindered and couldn't escape pressure from Detroit's defensive front the way he normally does. At one point he jogged to the sideline despite having open space to pick up extra yardage.
Willis said after the game his groin "felt a little tight," and coach Jeff Hafley agreed, saying you could see he wasn't able to open up and wasn't quite able to go full speed, though he credited Willis for still finding ways to escape trouble against a good defensive line.
Willis has completed 121 of 208 passes for six touchdowns and six interceptions this season. Kyle McCord will now start at quarterback for Miami.
