As seen moments ago on AEW Collision, a top star's undefeated streak on the Saturday show came to an end. This comes at a pivotal time as the promotion is only a week away from Full Gear.At the pay-per-view, Mark Briscoe will be challenging Kyle Fletcher for his TNT Championship in a no-disqualification match. The stakes are higher for this rematch because Briscoe's loss would result in him being forced to join the Don Callis Family.The faction has been trying to soften him up for The Protostar. A few days ago at Blood and Guts, members of the Don Callis Family were responsible for a backstage attack on The Sussex County Chicken just as he was about to enter the match. Tonight, he has been booked for a bout against Mark Davis.Davis has not lost a single match on AEW Collision and remains undefeated at 4-0. Interestingly, his fourth win was against Mark Briscoe back in March during the AEW International Title Eliminator Tournament.Tonight's Battle of the Marks was a physical contest, with Davis asserting his dominance in the strength category. Briscoe's unorthodox style of wrestling was what gave him the edge in this bout.Mark Briscoe is coming off a win at Blood and Guts, so he has all the momentum despite the Don Callis Family trying to derail him. He ended up scoring the win tonight after landing a Froggy Bow on Davis and broke his undefeated streak. This is a much-needed victory for him, and he has made a major statement to Kyle Fletcher.Briscoe also thrives in chaos, and this match at AEW Full Gear may be tailor-made for him. This looks to be one of the potential show-stealers at the pay-per-view, and one that may have a major impact on the roster moving forward.
