Dallas Cowboys wide receiver Michael Gallup is to undergo knee surgery and could be out for up to four weeks, according to the NFL Network's Ian Rappaport.
The 23-year-old will have a procedure to trim his meniscus after taking a helmet to the knee during Sunday's 31-21 win over the Washington Redskins at FedEx Field.
Gallup, a third-round pick in the 2018 draft, leads the Cowboys receivers for receptions this season with six. He is second in terms of receiving yards (68) to Devin Smith (74).
He could miss matches against the Miami Dolphins, the New Orleans Saints and the Green Bay Packers.
The Cowboys also saw starting nose tackle Antwaun Woods suffer a knee injury during Sunday's victory. He left the field and did not return with reports saying he has suffered a mild MCL sprain.
