New York Giants will relocate post-training signing sessions after several children were pinned against barriers as they tried to get the autograph of star wide receiver Odell Beckham Jr.
The Giants said no-one was injured when barriers "shifted" as fans clamoured for 22-year-old Beckham's signature.
But the NFL franchise said sessions at their training camp would be moved and limited to children aged 12 and under.
Last season, rookie Beckham scored 12 touchdowns in as many games.

According to reports, Beckham and team-mate Victor Cruz were quickly moved away from the autograph-hunters after the barriers shifted.
A YouTube video of the signing session also appeared to show a child being lifted from behind the barriers and into the arms of a security guard.
Beckham's profile is high heading into his second NFL season, helped in part by the increase in fame that followed his spectacular one-handed catch during a 31-28 loss to Dallas Cowboys last November.
Beckham also had nine games in a row with 90 or more receiving yards, matching an NFL record set by Cowboys star Michael Irvin in 1995.
