Richie Towell scored a hat-trick as Dundalk got back to winning ways to beat Derry City 3-0 at Oriel Park and regain second place in the Premier Division table and confirm their qualification for Europe.

Shels started well and were ahead from a freakish goal on 13 minutes when Derek Doyle scored direct from an in-swinging corner.
It got better for Shels ten minutes later when they stretched their lead. Drogheda didn't defend Robert Cornwall’s long throw and defender Paul Andrews’ low drive took a deflection to enter the net off a post.
Drogheda hit back on the half hour when Doyle was guilty of a push on Peter Hynes and Gavin Brennan smashed the resulting penalty down the middle.
Shels' keeper Lee Murphy then made a brilliant save to deprived Ryan Brennan before allowing a cross-shot from Gavin Brennan enter the net for Drogheda's equaliser on 61 minutes.
