Umpire raises his hand after LBW appeal, ends up rubbing his nose

Umpire Greg Davidson raised his hand to give the batsman out but changed his mind midway to end up rubbing his nose during a BBL match. Adelaide Strikers' Rashid Khan appealed for an LBW during 17th over and as Davidson started to raise his finger, Melbourne Renegades' Beau Webster started to walk. The umpire, however, declared him not out.
