Max Power netted Tranmere Rovers' winner in their FA Cup replay with Oxford United.
Tranmere will tackle Premier League opposition in Swansea thanks to a 2-1 victory over Oxford at Prenton Park.
Power netted a 76th-minute winner after team-mate Kayode Odejayi, who once scored a famous FA Cup winner for Barnsley against Chelsea, had cancelled out Oxford's opener from Alfie Potter.
