Dolphins running back Alexander Mattison’s season is over.

Mattison underwent season-ending neck surgery on Sunday in Chicago, according to Adam Schefter of ESPN. Mattison hurt his neck during Sunday’s preseason game against the Bears and had the surgery at a nearby hospital after the game.

The seriousness of the injury stands in contrast to what Dolphins head coach Mike McDaniel said after the game when he said he was doing well and had some neck and shoulder soreness, the story pointed out. Mattison was looking good early in camp according to reports, and seemed like he could be a viable change of pace and goal line option for Achane. The team was hosting Williams to perhaps take that role.
