Darfield lightweight Robbie Barrett won't box this weekend after sustaining a back injury in training.

Barrett, 23, who is the reigning Central Area champion, had been due to face Fonz Alexander from Newark at the Doncaster Dome on Saturday night but mentor Stefy Bull confirmed he's pulled out.

"These things happen in boxing," said Mexborough-based Bull.

"It's a shame for Robbie. We think it's a trapped nerve in the bottom of his back. Hopefully he won't be out too long."

Barrett has been on a winning run of five fights since March last year and now has a record of won nine, lost two, drawn one as a professional.

After beating West Melton's Brad Botham for the Central Area title earlier this year he made a successful defence against Huddersfield's Ismail Anwar in June.

Barrett's stablemate Andy Townend, from Cudworth, makes his television debut on September 5.

Power puncher Townend, 26, is looking to defend his English super-featherweight crown live on Sky Sports against Lee Glover from West Bromwich.

Bull hopes Townend, who has won 13 from 16 and stopped nine of his opponents, can impress enough on the show at the First Direct Arena in Leeds to earn a promotional deal with Matchroom Sports.

Professional boxing returns to Barnsley on September 18 with Monk Bretton's Ben Wager headlining at the Metrodome.

Wager, 25, takes on former foe Kofi Yates of Manchester for the Central Area light-welterweight title.

Also on the bill will be fellow Barnsley fighters Tony Cruise, Jack Churchill and Lee Gibbons.

Athersley South cruiser Cruise, 33, faces the most high profile contest against Liverpool's Carl Dilks, who once lost on a split decision for the Commonwealth title.
