Joe Ward remains the highest placed Irish male boxer in the new AIBA rankings for men for September.
The Moate BC southpaw, the current European Elite champion and World Elite finalist,is ranked No. 4 in the light-heavy class.
Walker, almost ironically, should be ranked No.23, as his former Irish team-mate, Michael Conlan, is still included in the rankings despite having switched codes and won four fights in the paid ranks.
Conlan and boxers who have turned pro, including Katie Taylor who is still ranked by AIBA, should be removed from the rankings
Dean Gardiner is ranked No. 47 at super-heavy.
World female rankings remain the same since being updated last July.
