Odell Beckham Jr. won't be available for the New York Giants in Week 1 of the regular season at the Detroit Lions.

Beckham could be out for the first two or three weeks of the season as he returns from a hamstring injury.

"Let's just let this kid get better," Tom Coughlin said after practice Monday. "I went to him yesterday to say, 'Let's just not have any more setbacks.' Because it's every day the same question over and over. He's not ready to play. He may be a couple or three weeks away. I'll let you know when he's ready."

Beckham missed the team's June minicamp with a hamstring injury and aggravated it in the team's first practice of training camp July 22.
