Odell Beckham Jr.'s ankle injury could potentially keep the New York Giants wide receiver out of the season opener, sources told ESPN's Jordan Raanan and Dan Graziano.

The Giants open their season on the road on Sept. 10 against the Dallas Cowboys.

It's "not out of the question he could miss a week or two of the regular season," according to one source.

Beckham left Monday night's game against the Cleveland Browns after taking a hard hit to the left leg from Browns cornerback Briean Boddy-Calhoun.
