Isaiah Crowell's season is over.
The Jets placed the injured running back on the injured reserve on Friday, per ESPN's Adam Schefter.
Crowell left Sunday's 27-23 win over the Bills with a foot injury and did not return. He was ruled out for Saturday's game against the Texans on Thursday after not practicing all week.
Crowell, 25, averaged 4.8 yards per carry and scored six touchdowns in his first season with the Jets.
He is under contract for two more years and owed $8 million. The Jets would save $3 million against the cap in 2019 if they chose to cut him in the offseason.
Crowell joins fellow running back Bilal Powell on season-ending injured reserve. Powell's season ended after seven games when he was required to undergo neck surgery.
Elijah McGuire, who rushed for 60 yards and scored the game-winning touchdown on Sunday, will be the Jets' lead back while De'Angelo Henderson could get promoted from the practice squad.
