Gerwyn Price, the Welsh darts player, has withdrawn from Thursday night’s Premier League Darts in Aberdeen due to a back injury. Under tournament rules, Price’s quarter-final opponent, Luke Humphries, will receive a bye into the semi-finals, gaining two league points and a +1 leg difference. Price, on the other hand, receives a -6 leg difference on the league table. Humphries will face the winner of the semi-final match between Michael van Gerwen and Rob Cross.
