Jason Roy scored a century before rain forced Surrey's Yorkshire Bank 40 clash with Durham at the Kia Oval to be abandoned.
The 22-year-old South Africa-born right-hander scored 117 from 111 balls as Surrey were bowled out for 216 after losing the toss and being put in to bat.
The hosts were skittled in 37.3 overs with Roy their eighth man out as Chris Rushworth returned figures of 4-44, while Ben Stokes and Paul Collingwood finished with two wickets each.
But the end of the innings was overshadowed by an injury to Stokes, who took a superb overhead catch to account for Roy but landed heavily on the outfield.
The Durham all-rounder lay prone for the next five minutes receiving treatment before being transferred to a stretcher and carried from the ground.
He was taken to hospital for scans, with Durham unable to confirm the extent of the injury although he seems certain to miss the LV= County Championship match between the sides which starts on Friday.
Surrey had earlier looked set for a storming start as in-form Steven Davies clattered a four and a six early on, but he was dismissed for 16 when he found a leading edge to be caught low down at mid-off.
Roy then teamed up for useful partnerships with Vikram Solanki (18) and Zander de Bruyn (24) before a middle-order collapse reduced them to 174-7.
Jon Lewis hit and unbeaten 24 from 16 balls to regain some momentum but the weather meant there was no chance for Durham to reply.
