Dolphins' Alexander Mattison: Season-ending injury, per report

Mattison reportedly underwent season-ending neck surgery Sunday, Adam Schefter of ESPN reports.

Further confirmation is needed from the Dolphins, but it looks like Mattison, who hurt his neck during Sunday's game against the Bears, is a candidate for IR. In Mattison's looming absence, look for the team to add depth to a backfield that also includes De'Von Achane, Jaylen Wright and Ollie Gordon. Per Schefter, Miami plans to host Jamaal Williams for a workout Monday.
