Lamar Odom Knocks Down Sparring Partner In New Training Vid For Aaron Carter Fight

Aaron Carter beat Shaq, but could be in big trouble when he boxes Lamar Odom … ’cause the ex-NBA star sent his opponent to the canvas in a recent sparring sesh, and TMZ Sports has the vid!!!

As we previously reported, AC and LO are training non-stop for their Celebrity Boxing fight on June 12 in Atlantic City … proving they’re serious as hell about the bout.

We’re told Odom has been hittin’ the mitts with Barry Young at Decatur Boxing in ATL this week … and it’s obvious Lamar’s putting in the work — he even knocked the guy down at one point!!

Remember, we obtained a vid last week of Carter going HAM in the gym … working with MMA fighter Jesse Strader.

Now, we’ll keep it a buck — these guys aren’t gonna be Tyson Fury overnight … but it’s obvious they’ve got a passion for kickin’ ass, and it looks like they’ll be ready to go at it come June.

Both guys have guaranteed a victory … but only one will come away with the dub.
