We didn't see any title change hands at NJPW Power Struggle over the weekend, but there were a couple of major returns which set up a pair of big matches for Wrestle Kingdom 14 on January 5.
The first occurred after Kota Ibushi and Hiroshi Tanahashi defeated Kazuchika Okada and YOSHI-HASHI in a tag-match. AEW Champion Chris Jericho appeared on the screen in his Painmaker guise to challenge Tanahashi to a fight at the 2-day event, promising that it's going to be The Ace's final match.
We haven't seen Jericho in New Japan since he lost to Kazuchika Okada at Dominion back in June, but he's clearly taking advantage of a deal that allows him to compete for both AEW and NJPW.
