The World Championship last-16 tie between John Higgins and Xiao Guodong is set for a dramatic late-night finish with the Scot needing one more frame to reach the quarter-finals.
Only seven of a potential nine frames could be completed in time before the afternoon session was scheduled to begin at 14:30 BST with Higgins leading 12-11 in the first-to-13 match.
Higgins had a glorious chance to wrap up the tie as he led 53-33 in the 23rd frame but missed a black off the spot before Xiao kept his tournament hopes alive.
That means they will have to play to a finish later on Saturday, resuming on the first available table after the scheduled evening matches have taken place.
