Running back Alexander Mattison‘s time with the Minnesota Vikings came to an abrupt conclusion Thursday, when the team indicated its plans to release him after five seasons on its roster, a source told ESPN’s Adam Schefter.

The decision capped a disappointing year after Mattison failed to hold down the starting job following the departure of longtime lead back Dalvin Cook. The move will save the Vikings $3.35 million against their 2024 cap. Had he remained on the roster past March 15, Mattison would have had $2.75 million guaranteed for the 2024 season.

The Vikings’ third-round draft pick in 2019, Mattison spent four seasons as Cook’s backup before signing a two-year contract worth up to $7 million in March 2023. The Vikings released Cook later that spring and elevated Mattison, hoping he could provide strong inside running even if he couldn’t match Cook’s explosiveness.
