FRISCO, Texas -- Dallas Cowboys wide receiver Michael Gallup will have arthroscopic surgery on his left knee on Tuesday that could force him to miss two to four weeks, coach Jason Garrett said on Monday.
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. He had a career-high 158 yards on seven catches in the season opener against the New York Giants.
