The goals by Daniel Munoz and Justin Devenny saw Crystal Palace until the fifth round of the FA Cup 2-0 in Doncaster.
The Eagles avoided a disruption to the Eco-Power Stadium to create a tie in Millwall, despite being struggling to create chances against a well-organized Rovers outfit that failed to make the most of their own opportunities.
Colombia’s wing Munoz eventually discovered a well -edited free kick before Northern Ireland’s international Devenny put the game beyond the reach early in the second half.
Rovers was the first to make an effort for the target, as good work under James Maxwell and Luke Molyneux led Billy Sharp to remove the ball for Ethan Ennis, whose plum shot from the edge of the area, saved, saved, Comfortable by Matt Turner.

The palace proceeded with the first opportunity to be noted in the 31st minute. Daichi Kamada’s smart kick found Jean-Philippe Mateta, whose shot behind the post, but left Munoz with a simple fountain.
The Rovers continued to keep their own and Molyneux and Rob Street in combination to find Sharp, whose turn was kept by Turner.
Oliver Glasner brought Ben Chilwell in the half for his debut in his palace, as full -back England played his first minutes since he appeared as Chelsea’s substitute in a Carabao Cup tie against Barrow in September.
