Beckham posts video claiming 'I'm back' days before mandatory camp

Odell Beckham Jr. has been mysteriously missing from the New York Giants' voluntary mini camp, but with the team expecting his return this week, it appears the star will be reporting.

Beckham posted a video to Instagram on Sunday of his offseason workout routine with the caption "I'm back."

Along with Beckham, defensive end Olivier Vernon was not in attendance for the Giants' minicamp, which ran intermittently from May 22 to June 9.

Head coach Ben McAdoo said on the final day of voluntary sessions that he expects "everyone" to report for mandatory camp, beginning June 13.

It was reported that Beckham's absence was due to his desire for a new contract, which is expected be a record-setting deal when it happens. The receiver, however, has little leverage with two years remaining on his rookie contract.
