Alexander Mattison: Everything you need to know

Dolphins coach Mike McDaniel said Tuesday that Mattison (neck), who was placed on season-ending IR on Monday, does not have a career-ending injury, David Furones of the South Florida Sun Sentinel reports. Mattison suffered a neck injury during Sunday's preseason tie against the Bears that required surgery, and will cause him to miss the entire 2025 season. It's encouraging that Mattison may be back in action for the 2026 campaign, though given that he inked only a one-year deal with Miami this offseason, it's likely that his next opportunity will come with another organization. With Mattison on IR, both second-year pro Jaylen Wright and rookie sixth-rounder Ollie Gordon benefit from a clearer path to touches behind starter De'Von Achane.

The Dolphins placed Mattison (neck) on injured reserve Monday. Mattison emerged from Sunday's preseason tie with the Bears with neck soreness and then reportedly underwent neck surgery not longer afterward, per Adam Schefter of ESPN. With Mattison's move to IR, the severity of the injury more or less has been confirmed, and he'll miss the 2025 season, barring getting cut with an injury settlement. Both Jaylen Wright and rookie Ollie Gordon now both have clearer paths to locked-in reserve roles behind Miami's top RB De'Von Achane.

Mattison reportedly underwent season-ending neck surgery Sunday, Adam Schefter of ESPN reports. We'll await further confirmation 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 his 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.
