Goals from Daniel Munoz and Justin Devenny saw Crystal Palace through to the FA Cup fifth round with a 2-0 win at Doncaster.
The Eagles avoided an upset at the Eco-Power Stadium to set up a home tie against Millwall, despite struggling to create chances against a well-organised Rovers outfit who failed to make the most of their own opportunities.
Colombia wing-back Munoz eventually made the breakthrough from a well-worked free-kick before Northern Ireland international Devenny put the game beyond reach early in the second half.
Rovers were first to get an effort on goal as good work down the left by James Maxwell and Luke Molyneux led to Billy Sharp laying the ball off for Ethan Ennis, whose tame shot from the edge of the area was comfortably saved by Matt Turner.

Palace went ahead with their first chance of note in the 31st minute. Daichi Kamada’s clever low free-kick found Jean-Philippe Mateta, whose shot cannoned back off the post but left Munoz with a simple tap-in.
Rovers continued to hold their own and Molyneux and Rob Street combined to find Sharp, whose shot on the turn was held by Turner.
Oliver Glasner brought Ben Chilwell on at half-time for his Palace debut as the England full-back played his first minutes since appearing as a substitute for Chelsea in a Carabao Cup tie against Barrow in September.

However, just as the League Two promotion chasers looked to be building some momentum, Palace launched a 55th-minute break and Hughes played a clever ball over the top to allow Devenny to convert a second.
Doncaster could have pulled one back on the hour mark but Molyneux shot straight at Turner after being cleverly played in by Sharp but now bow out of the competition.
