Sean Brady may have made his case for a welterweight title shot -- or at worse, be one step away from a title shot -- after finishing former champion Leon Edwards in the main event of UFC London.

Edwards appeared to get to a head start after the first round. He defended Brady's takedown attempts more than once and focused on attacking the body in the meantime. The American, to his credit, landed a solid flurry during the round and scored a late takedown.

From side control, the Philadelphia standout then looked for a kimura. Brady managed to work his way into full mount and to the back of Edwards, landing ground-and-pound against the Brit's movement and defenses.

Brady pressed forward at the start of the third round. Edwards went for a takedown of his own and got caught, with his opponent threatening a choke for several seconds. Brady got back into full mount, eventually landing several head shots that cut open the former champion. Brady continued to dominate with top control, overwhelming and controlling a tiring Edwards.

The fight found its way back to the ground in the fourth, where Brady was able to quickly lock up a guillotine choke and score a submission.

Sean Brady has now won three straight, with the sole loss in his professional MMA career coming against the current welterweight champion, Belal Muhammad.
