Dallas Cowboys wide receiver Dez Bryant has been ruled out for up to six weeks after breaking a bone in his foot in his side's 2015 season opener.

The 26-year-old sustained a broken metatarsal in his right foot in the third quarter of the Cowboys' win over the New York Giants, which will require surgery to repair.

Head coach Jason Garrett has conceded that the All-Pro will face at least a month out due to the injury.

"We want to be careful about making the entire judgment on it, but Dez did break a bone," Garrett told reporters. "We anticipate him having surgery. The initial diagnosis is he'll be out four to six weeks."

Bryant made five receptions for 48 yards in the win at AT&T Stadium.
