Giants GM Jerry Reese admitted the team is concerned about first-round rookie WR Odell Beckham's "tweaked" hamstring.
"He missed part of spring ball with a hamstring and he tweaked it yesterday. Obviously there is a concern," Reese said. Beckham first injured the hammy in the spring, and then re-tweaked it on his first route on the opening day of training camp Tuesday. Coach Tom Coughlin said after Wednesday's practice that he has no idea when Beckham will be back on the field. Rookie receivers tend to struggle in year one anyway, so any missed practice time for Beckham is a concern. Jerrell Jernigan ran with the starters in three-wide sets on Wednesday.
