Michael Conlan says he "paid the price" for a slow start against Luis Alberto Lopez after suffering world title heartache for a second time on Saturday night.
The 31-year-old's dreams of becoming IBF featherweight king were felled by champion Lopez who retained his crown with a devastating stoppage win at the SSE Arena.
Conlan was floored by a vicious uppercut in the fifth round, prompting the towel to be thrown in by his coach Adam Booth.
