8:52 AM PT -- TMZ Sports has obtained footage from the surveillance video which appears to show Donald pulling people off of Spriggs after the alleged bottle attack.
Aaron Donald's lawyer claims the NFL superstar was the target of a bottle attack outside of a nightclub ... and he's got video to prove it.
Donald's attorney, Casey White, claims the assault allegations levied against the L.A. Rams superstar are provably false based on surveillance video they've obtained along with multiple witnesses.
As we previously reported, DeVincent Spriggsfiled a police report against Donald -- claiming Aaron beat the daylights out of him outside the Boom Boom Room nightclub in the early hours of April 11.
But, Casey White appeared on 93.7 The Fan in Pittsburgh on Friday morning and says the surveillance video proves Spriggs is 100% full of crap.

White says the two were at a party together at a residence above the nightclub when Spriggs bumped into Donald -- elbowing him in the back.
White says there was a minor conflict which resulted in Spriggs being kicked out of the party.
But, Spriggs allegedly waited for Donald in an alley outside -- that's when he tried to attack with a bottle.
"Mr. Spriggs starts walking toward Aaron and he's yelling and he's drunk and he's aggressive," White says.
"And, Aaron sees something in his right hand and first he thinks it's a gun."
"But, it's actually a bottle, a long liquor bottle. In fact, [Spriggs] swings with his right hand, Aaron ducks. The bottle grazes the top of Aaron's head ... he has a lump on his head from the bottle."
At that point, White says people in the area -- including Aaron's brother -- raced in to help Aaron and some people began beating Spriggs savagely.
Aaron was restrained during the beating, White says -- but eventually freed himself and actually began ripping people off of Spriggs.
"He actually saved Mr. Spriggs from further injury,” White said ... "It’s fantastic, from a defense attorney’s perspective, to be honest with you."
White says Spriggs was badly injured -- but insists the guy only has himself to blame.
White also claims he received an email from police saying investigators do not have any video evidence showing Donald assaulted Spriggs -- the implication being Donald will NOT be charged with a crime.
White also suggested he would be releasing footage soon to show everyone Donald did nothing wrong.
