FRISCO, Texas -- Dallas Cowboys wide receiver Michael Gallup is facing arthroscopic knee surgery that could force him to miss two to four weeks, according to multiple sources.
Gallup is seeking a second opinion before a determination is made on the surgery, according to sources, but the operation could happen as soon as Tuesday.
Gallup suffered the injury during the fourth quarter of Sunday's 31-21 victory over the Washington Redskins. While there was optimism after the game, further testing Monday revealed a cartilage issue.
Through two games, Gallup leads the Cowboys with 13 receptions for 226 yards.
