Dallas Cowboys wide receiver Amari Cooper underwent an MRI on his knee and was not expected to practice Thursday, coach Jason Garrett announced.
Garrett said the Cowboys (5-3) are still hopeful that Cooper can practice Friday and play Sunday night against the Minnesota Vikings (6-3) in Arlington, Texas.
Cooper, who had the MRI on Wednesday, sustained the injury last week in practice and aggravated it during Monday's 37-18 victory over the New York Giants.
The 25-year-old Cooper, who also has dealt with foot, ankle and quadriceps injuries this season, had four receptions for 80 yards and a touchdown against the Giants.
Cooper leads the team in catches (42), receiving yards (701) and receiving scores (six) this season.
The three-time Pro Bowl selection has 320 receptions for 4,609 yards with 31 touchdowns in 69 career games with the Cowboys and Raiders since being selected by Oakland with the fourth overall pick of the 2015 NFL Draft.
