Early risers Stephen Hendry and Mark Williams booked their places in the quarter-finals of the China Open in Beijing this morning.
The two highest-ranked players left in the event were required to play their matches early but they needed little time to race into the last eight.
World number three Hendry compiled four half-century breaks to beat Ryan Day 5-1, while Williams knocked in two centuries as he defeated Adrian Gunnell 5-2.
Steve Davis was taken to hospital for an X-ray after conceding his match with Ricky Walden.
Davis (47) banged his head on a steel door after signing autographs shortly before the game and felt light-headed as the match got underway.
At the end of the third frame, referee Eirian Williams escorted him to the tournament office where Davis was given a painkiller.
However, he felt worse as frame four began and conceded it trailing 11-1 with Walden on a break of seven.
Davis, who was 3-0 down in the match, was examined by a doctor at the venue before being taken to a nearby hospital for an x-ray.
