Joshua 'would rather lose' than be a doper

LONDON - Anthony Joshua believes he would be forced to quit boxing if the unified heavyweight champion ever endured the kind of doping scandals that have engulfed Alexander Povetkin.

Povetkin's standing as the mandatory challenger for British star Joshua at Wembley on Sept 22 has infuriated fans, who feel the Russian shouldn't be allowed back on the big stage after his drug issues.

In May 2016, the 38-year-old tested positive for meldonium - the same banned substance compatriot Maria Sharapova was suspended from tennis for taking.
