According to PW Insider's Mike Johnson, Luchasaurus has an injured hamstring and is out of Wednesday's tag team championship tournament match on AEW Dynamite.
Filling in to team with Jungle Boy is fellow Jurassic Express member Marko Stunt. The duo will face the Lucha Bros (Pentagon Jr and Fenix) in a first round bout.
Johnson said the call was made to pull the big man from the match this afternoon so he wouldn't further aggravate the injury.
AEW debuts in Philadelphia tonight with that match, Best Friends vs. SCU in another first round tag tourney match, AEW women's champion Riho defending against Britt Baker, Jon Moxley and PAC vs. Adam Page and Kenny Omega, and AEW World Champion Chris Jericho vs. Darby Allin in a street fight for Jericho's title.
Last week in Boston, Private Party advanced to the semifinals with a win over The Young Bucks and will face the winner of the Jurassic Express-Lucha Bros match while the Dark Order earned a first round bye and will face the winner of SCU vs. Best Friends.
