A$AP Rocky Sued By Fan at Backbreaking Concert

A$AP Rocky is being sued by a fan who was horribly injured during a concert, but it looks like the rapper was targeted not because of anything he did ... he's just got the deepest pockets in his mob.

Krystina Clowes claims in a new lawsuit she was enjoying the performance of A$AP Ferg during the 2013 concert when she was drilled into the ground, suffering a fractured vertebra.

Turns out ... A$AP Mob member Young Shabba felt the urge to crowd surf and landed on the unsuspecting fan. She says in the lawsuit she's a mess, and may never fully recover.

As for why she's suing A$AP Rocky, Clowes claims the whole mob has a history of stage diving, so they're all responsible.

She wants $75k minimum, and it appears a whole lot more.
