Mathews had put Lindsay down in the 2nd round and was ahead on points, until a knockout brought any aspirations that Mathews may have had of fighting for the British title down.^[5] Mathews second fight with Hayemaker in March 2009 took place in his home town of Liverpool. It also ended in disappointment as he suffered a stoppage defeat to Harry Ramogoadi.^[6] Following the collapse of Setanta Sports and the loss of Hayemakers television deal, Mathews split from the promoter saying "It’s a shame but after the TV went the shows dried up.
