Non-League Chorley claimed an unlikely place in the FA Cup fourth round as they proved too strong for a youthful Derby side in an extraordinary tie. Connor Hall and Mike Calveley were the men on target as the National League North side claimed a 2-0 victory in what was theoretically an upset on a freezing afternoon in Lancashire.

Yet with the Championship visitors decimated by a Covid-19 outbreak at their club, the four division gap between the sides was wiped out, handing the initiative to the part-timers. Derby, with interim manager Wayne Rooney and their entire first-team squad isolating, were forced to field a team made up from their youth sides in order to fulfil the fixture. With an average age of just 19 and not a single game of first-team experience amongst them, it was an uphill struggle.

That the game went ahead was remarkable in itself. Quite apart from the coronavirus issue, sub-zero temperatures in Chorley over the past week had forced the sixth-tier side to rent covers to try to prevent their surface from freezing. Their groundsman even camped at the ground in a tent to try to keep the pitch heated overnight. His efforts proved worthwhile as the Magpies seized the opportunity to make history for their club and took the game to a team they ordinarily might not have been able to compete with.

The fourth and fifth-round draws will both take place on Monday evening and Chorley will now be hoping to meet a Premier League name.

• Everton were another big name struggling on Saturday afternoon having been pushed to to extra-time by Rotherham, but eventually came through thanks to substitute Abdoulaye Doucoure’s 93rd-minute goal.

• Lyle Taylor ended his longest goal drought since October 2017 to fire Nottingham Forest into the fourth round with a 1-0 win against Cardiff. The former Charlton striker – one of eight changes made by home boss Chris Hughton following last weekend's win at Preston – took less than three minutes to claim the only goal of the game and his first in 13 outings. Away boss Neil Harris could only watch from the stands due to a touchline ban as his side showing four changes suffered a fourth straight defeat.

• Norwich scored two early goals to see off fellow Championship side Coventry 2-0 in a low-key third-round tie at Carrow Road. An assured sixth-minute finish from Kenny McLean and a firm header from Jordan Hugill 80 seconds later settled a game that rarely hit the heights after an exciting start. Coventry had their moments but found young goalkeeper Daniel Barden in good form and could have few complaints about the final outcome.

• Millwall avoided a potential banana skin at Meadow Park as they comfortably overcame Boreham Wood 2-0 to advance to the fourth round.

• George Moncur scored the only goal of the game as Luton beat fellow Championship side Reading. The midfielder volleyed the only goal of the third-round tie in the first half to decide the contest at Kenilworth Road.
