Sexton is currently trained by Paul Rees and is managed by London promoter Michael Helliet.

[1] Sexton made his professional debut in Watford, England on 1 August 2008, defeating David Keogan in a 4 round contest.

[3][4] Following the Ahmed win, Sexton challenged reigning British flyweight champion Shinny Bayaar.

After losing many of the initial rounds, Sexton began to dominate later on as Shinny Bayaar struggled with a cut injury.

The fight, at the Goresbrook Leisure Centre in Dagenham, was scored a draw, although a number of observers felt that Bayaar might have done enough to win.
