The hip-hop stars were performing at the BB&T Pavilion in Camden, New Jersey on 5 August (16) as part of their The High Road Tour, when a railing which separated the pavilion's lawn from inside seating gave way, causing dozens of fans to fall several feet to the concrete floor.

Snoop and Wiz had asked for fans to "stand up" moments before the incident, causing the crowd to push forward, according to officials. The hitmakers were quickly escorted off stage by security staff, and the remainder of the concert was subsequently scrapped.

At the time, Camden police spokesman Dan Keashen confirmed more than 40 people had been injured in the accident, with many hospitalised with broken bones, scratches and bruises, and later in August, 17 of them teamed up to sue for compensation.

Now the duo have been hit with another lawsuit, from a woman who claims her 16-year-old granddaughter's competitive cheerleading career has been halted because of the injuries she sustained amid the railing collapse.

According to the legal documents, obtained by TMZ.com, the teenager fell 10 feet onto a concrete floor, where she was pinned by the crowd and knocked out. She woke up with a broken arm and wrist, and covered in blood, and has been having nightmares since the incident, her grandmother claims.

The woman is also suing concert promoter Live Nation, which manages the venue, claiming they had inadequate crowd control.

Live Nation had no comment when contacted by TMZ, while representatives for the musicians have yet to respond to the lawsuit.
