The match card for WrestleMania 40 is gradually coming together on a weekly basis through weekly episodes of Raw and SmackDown. One more match is reportedly in the pipeline where two factions would get involved in a massive brawl.
According to Xero News, there are plans for a Philadelphia Street Fight between Karrion Kross' Final Testament faction (including the members of The Authors of Pain) and Bobby Lashley's faction (including the members of The Street Profits).

Scarlett and B-Fab are also expected to be a part of this match at WrestleMania 40. A singles match between Kross and Lashley was also assumed but it's been ruled out since the two already locked horns on SmackDown.
Bobby Lashley missed The Show of Shows, last year despite being one of the top stars of the roster but he should feature on the card, this year. He was scheduled to face Bray Wyatt at WrestleMania 39, but the match got cancelled.
It didn't happen due to Bray's illness and the Superstar ultimately passed away. All Lashley did at last year's WrestleMania was appear on the stage with the Andre The Giant Memorial Battle Royal trophy that he won on SmackDown before 'Mania.
In more update, WrestleMania 40 is approaching closer and ticket sales are also nearing 60,000 for each night with just a few slots available. It seems more tickets are sold for Night Two in comparison to Night One.
According to WrestleTix, WrestleMania Saturday has sold 58,593 tickets, while WrestleMania Sunday has sold 59,861 tickets. The host venue of the PLE has been set up for a seating capacity of 60,910, meaning not even 2,000 tickets are left to sell.
Despite WWE keeping high prices, tickets are in demand, even for those seats with limited views behind the stage. The cheapest tickets are available at $200 for seats in the rafters and limited view sections, while the high-priced tickets are available at $450.
