Kiefer Crosbie Record: 10-6-0

Bellator run and the road back

Crosbie's deepest body of work came in Bellator, where he went 4-3 against a step up in competition. The lone blemish that still stings on paper was a 2019 disqualification loss to Mike Jackson by way of an illegal knee, a frustrating end to a fight rather than a clean defeat. He answered with decision wins over Hugo Pereira and Iamik Furtado before back-to-back stoppage losses to Charlie Leary and veteran Georgi Karakhanyan tested his standing. To force his way into the UFC conversation, he rebuilt on the regional circuit, including a statement first-round TKO of former UFC veteran Alex Oliveira in April 2023.

UFC tenure

Crosbie made his UFC debut in September 2023 at UFC 293, where he ran into Kevin Jousset and was caught in a first-round rear-naked choke. The Octagon has proven a difficult proving ground: he was submitted again the following year by an arm-triangle choke from Sam Patterson at UFC 304 in July 2024, then stopped by Taiyilake Nueraji via first-round TKO on elbows in August 2025. The trio of losses underlines the brutal margins at the sport's top level, but also Crosbie's willingness to keep taking tough assignments rather than padding his ledger.

Fighting style

Crosbie is a pressure-based striker first, and the math backs it up: of his 10 wins, five have come by knockout or TKO and two by submission, a 70% finish rate that speaks to a fighter who comes to end things. His best work comes in the clinch and along the fence, where his elbows have produced several of his stoppages. The flip side is on the canvas – all three of his submission losses and a pair of his setbacks have come on the ground, exposing a grappling and scramble defense that elite opposition has been able to target. At his best, he is a dangerous, aggressive finisher; the challenge has been keeping fights in the spaces where he thrives.
