Dolphins RB Alexander Mattison placed on season-ending injured reserve after neck surgery

Miami Dolphins running back Alexander Mattison has been placed on season-ending injured reserve after undergoing neck surgery. Mattison, who was acquired by the Dolphins during the offseason, sustained the injury during the team's first preseason game. The injury is a significant setback for the Dolphins, as Mattison was expected to play a key role in the team's offense this season. The 24-year-old running back had previously spent four seasons with the Minnesota Vikings, where he served as a backup to Dalvin Cook. With Mattison sidelined, the Dolphins will need to rely on their other running backs, such as Raheem Mostert and Jaylen Waddle, to carry the load in the backfield. The team's coaching staff will also need to adjust their game plans and offensive strategies to account for the loss of Mattison. The news of Mattison's season-ending injury is a disappointing development for the Dolphins as they prepare for the upcoming NFL season.
