Four-time champion John Higgins suffered a shock 10-6 defeat by Mark Davis in the first round of the World Championship at the Crucible.

Higgins led 2-0 but the world number16 from Hastings forged 6-3 ahead overnight, with breaks of 85 and 96.

The Scot won two of the first three frames on Monday with runs of 92 and 69, but errors allowed Davis to move within one of victory.

Higgins pulled a frame back but Davis made a composed 87 break to go through.

In what turned into a long drawn out match, 2006 world champions Graeme Dott overcame Englishman Peter Ebdon 10-6 in a match that was completed after the end of the programmed evening session.
