Matt Jackson of the Young Bucks has a partially torn MCL and thinning of the ACL, considered a slight tear.
Bryan Alvarez reported the injuries on Wednesday's Wrestling Observer Radio, explaining that is why Jackson has been selling an injury caused by FTR Pillmanizing his ankle on a recent Dynamite.
Alvarez said Jackson suffered the injury in a July falls count anywhere match he and Nick Jackson had with The Butcher & The Blade. On the match-ending flying elbow spot off the set onto the stage (pictured above), the table leg jammed up his knee. He has been rehabbing it ever since, apparently avoiding surgery. The team has worked in eight matches since the injury.
Dave Meltzer noted this isn't the first time Jackson has taken a real life injury and turned it into a storyline, referencing a back injury he had while still with New Japan Pro Wrestling.
The Bucks will face FTR for the AEW Tag Team Titles on Saturday's Full Gear pay-per-view and if they lose, they will never challenge for the belts again.
