West Ham stemmed the flow of upsets in the fourth round of the FA Cup by beating third-tier Bristol City 1-0 thanks to Diafra Sakho's late header on Sunday.
The Senegal international leaped high to meet a deep cross from fellow striker Andy Carroll, planting a firm header just inside the post in the 81st minute.
Chelsea and Manchester City were among five teams in the Premier League's top nine to be eliminated on Saturday on one of the most astonishing days in the famous competition's history.
West Ham toiled in the first half at Ashton Gate, clearing two headed attempts off the line, but improved after the break. Sakho, a substitute, struck the bar before scoring.
Arsenal and Aston Villa face lower-league opposition later Sunday.
