Mark Selby looked uncomfortable in an awkward moment live on BBC Sport shortly after he crashed out of the World Snooker Championship against qualifier Joe O’Connor. The four-time world champion fuelled speculation about his future after suffering a first-round exit for just the fifth time in his storied career.

Selby’s struggles on and off the table this season have conjured the prospect of retirement, and he set those suggestions ablaze by confirming he had thought about calling it quits earlier this month.
