Crystal Palace dumped London rival Tottenham out of the FA Cup on Sunday with a 1-0 victory, while West Ham came from behind to beat Blackburn 5-1 to reach the quarterfinals.

Martin Kelly hit the decisive goal for Crystal Palace at White Hart Lane just before halftime, controlling a pass from Wilfried Zaha before lashing past Michel Vorm from inside the penalty area.

Tottenham came close to equalizing in the second half through Christian Eriksen, who was denied by a smart save from Palace goalkeeper Wayne Hennessey, and Alan Pardew's side held on for a narrow victory.

Earlier on Sunday, West Ham avoided an fifth-round upset with a comeback victory at second-tier Blackburn in a match that both sides finished with 10 men.

Ben Marshall put the hosts ahead with a low, left-footed strike after 20 minutes, before Victor Moses equalized for the Hammers after a run from the halfway line six minutes later.

Dimitri Payet put West Ham ahead with a free kick from 25 yards (meters).

Emmanuel Emenike then struck twice in the second half to make West Ham safe, before Payet got his second goal in stoppage time.

Chris Taylor was sent off for Blackburn and Cheikhou Kouyate for West Ham, both in the second half.

"After the first 20 minutes we played fantastic," West Ham manager Slaven Bilic said. "We played really great football and it looked easy."

Chelsea hosts Manchester City in Sunday's other FA Cup game. Third-tier Shrewsbury hosts Manchester United on Monday.

The quarterfinal draw is held later Sunday.
