EAST RUTHERFORD -- It was one thing for rookie wide receiver Odell Beckham Jr. to sit out minicamp with a slight hamstring pull. The Giants and their first-round pick were being cautious.
But one practice into training camp, Beckham pulled up lame again after getting his feet tangled with cornerback Dominique Rodgers-Cromartie. He pulled up on the play, which didn't seem to please coach Tom Coughlin.
Beckham was on the field Wednesday with his helmet and pads, but did nothing aside from stretching and warmups. It admittedly has the Giants concerned.
"He missed part of spring ball with a hamstring and he tweaked it yesterday. Obviously there is a concern," general manager Jerry Reese said. "But you see that in some young players sometimes. They're a little bit nervous, a little bit anxious and that happens to them."
The Giants have no idea when Beckham will return at full strength. They're hoping sooner rather than later, but a hamstring problem (as they've already seen) is something that can linger. The same hamstring that is bothering Beckham now is the one that gave him trouble in the spring.
Beckham was originally hurt in Organized Team Activities (OTAs). He came back to do a little during minicamp and now re-injured the hamstring early in training camp.
It has coach Tom Coughlin worried as well.
"Now, who knows how long," Coughlin said on Wednesday. "Those hamstrings, don't ask me. I have no idea. ... He missed today. He said it's sore. That is about all you can ask."
The Giants are looking for big things from Beckham. He was the 12th-overall pick in this year's draft. They were hoping his speed could stretch the field for an offense that struggled to make big plays last year.
Beckham was expected to, at the very least, compete for a starting job. He was working at the X-receiver spot in their offense, along with Jerrel Jernigan. If the hamstring continues to nag, it puts Beckham at a serious disadvantage.
Coughlin isn't a fan of putting players who can't practice into games. He's also traditionally brought rookies along slowly, although the idea was to have Beckham contribute immediately.
"This guy has that track speed and hopefully he can get back out there quickly," Reese said, "because we're expecting big things from him."
