While giving evidence on Tuesday, Sologinkin, 41, denied touching the woman on her vagina on the outside of her clothing in the crowded Treasury Casino in Brisbane.

The father-of-three played first-grade rugby league between 1997 and 2003, with stints at the South Queensland Crushers, Canberra Raiders, Canterbury Bulldogs and Melbourne Storm.
