Dallas Cowboys wide receiver Amari Cooper was diagnosed with a thigh bruise after being forced to leave Sunday's loss to the New York Jets in the first half, a source told Ian Rapoport of NFL Network.
While the injury can be severely painful, there is no indication of long-term damage, added Rapoport.
Without their top receiver, the 3-3 Cowboys suffered their third straight loss.
Cooper leads the Cowboys in catches (33), receiving yards (515), and touchdowns (five). It would be a major blow to the NFC East club's offense if the wideout were to miss time.
Dallas is embarking on a vital divisional stretch of its schedule. The Cowboys play the Philadelphia Eagles on Sunday night in Week 7 before traveling to face the New York Giants in Week 9 following a bye.
