Dallas Cowboys wide receiver Amari Cooper underwent an MRI on his injured knee Wednesday and missed practice Thursday, according to Michael Gehlken of the Dallas Morning News.
NFL Network's Ian Rapoport added that the MRI was precautionary and Cowboys head coach Jason Garrett "sounded optimistic" about Cooper's chances of playing against the Minnesota Vikings on Sunday night.
Cooper played through the knee ailment Monday night and finished with four receptions for 80 yards and a touchdown in Dallas' 37-18 win over the New York Giants.
