The UFC Edit
He lost his most recent fight versus undefeated heavy handed Travis Browne, a UFC newcomer. He is in danger of being cut from the promotion's roster.
McSweeney has decided to drop to the light-heavyweight division where he will face the newcomer Tom Blackledge. Blackledge dropped out of the fight with an injury about two weeks before the fight and he was replaced by another UFC newcomer, the highly touted Fabio Maldonado.
McSweeney looked good in the first round but he punched himself out and he was gassed a minute or two into the second round. The second was a round in which Maldonado completely dominated. Maldonado taunted the exhausted McSweeney openly in the third round and finished him via standing TKO in the third. McSweeney was afterwards cut from the ranks of the UFC after the two back-to-back losses.
