Crystal Palace booked their place in the FA Cup quarter-finals after overcoming 10-man Millwall.
The visitors were reduced to 10-men in the early stages of the match with Liam Roberts sent off for a high challenge on Palace forward Jean-Philippe Mateta.
Mateta required lengthy treatment before being taken to hospital on a stretcher.
Palace took the lead when Millwall's Japhet Tanganga inadvertently headed a cross into his own net.
Daniel Munoz's doubled the Eagles' advantage, before Millwall's Wes Harding pulled a goal back deep into stoppage time at the end of the first half.
