Play has been suspended in the fourth-round Wimbledon clash between Tomas Berdych and Jiri Vesely.
The Czech duo were about to enter a fifth set with a place in the quarter-finals at stake when the umpire called time on the contest due to poor lighting.
The match was tied at two sets each when play was suspended, with Vesely taking the opener 6-4 before Berdych levelled things up by claiming the second set 6-3.
Tie-breakers were required to decide sets three and four, with Berdych winning the first of them 10-8 and his opponent edging the latter 11-9.
The deciding set will be played on Tuesday morning.
