Joshua braced for 'toughest test since Klitschko clash'

LONDON - World heavyweight champion Anthony Joshua expects his title defense against Russian Alexander Povetkin on Saturday to be his toughest fight since Wladimir Klitschko - and to end with a similar outcome.

Joshua, 28, knocked out Ukrainian Klitschko at Wembley in April 2017 and the 2012 Olympic champion is returning to England's national stadium for the first time for his 22nd professional fight.

Povetkin, the 2004 Olympic super-heavyweight champion and WBA's mandatory challenger, lost to Klitschko in Moscow in 2013 - the only defeat in the 39-year-old's pro career to date.
