The Addicks host Cray Valley PM in the first round of the FA Cup on Sunday evening, live on BBC Two (KO 5.30pm GMT).
Five tiers and four miles separate the two teams in a cup tie that embodies what the prestigious cup competition is all about.
Michael Appleton’s side go into the game on the back of a 3-2 triumph at Wigan Athletic in midweek thanks to Alfie May's brace and Corey Blackett-Taylor's cool finish.
Tayo Edun (hamstring) and Conor McGrandles (knee) could both return to action this weekend, though Panutche Camará (hamstring) is set for a significant spell on the sidelines.
Harry Isted (knee), Terry Taylor (ankle) and Chuks Aneke (hamstring) remain absent for the Addicks.
It has taken Cray Valley PM five rounds of qualifying and eight games to set up Sunday's clash with Charlton. The Millers claimed a 5-2 win over Enfield Town at the Artic Stadium in the fourth and final round of qualifying.
Due to their FA Cup exploits, Steve McKimm’s men have only played five league games this term and are unbeaten, recording three wins and two draws so far to leave them sat 10th in the Isthmian League South East Division.
Sunday’s FA Cup tie will be the first ever meeting between the two sides.
The Millers have qualified for the first round proper on one previous occasion during the 2020/21 campaign, when they suffered a 1-0 defeat away to Havant & Waterlooville.
Benjamin Speedie will take charge of proceedings on Sunday. The official, who last refereed a Charlton fixture in February 2023, has overseen nine matches so far this season, showing 29 yellow cards and three red cards.
Speedie will be assisted by Ryan Whitaker and Gareth Viccars, while Tom Reeves is the Fourth Official.
Please note the club's Ticket Office will be open from the later time of 1pm on Sunday afternoon.
Bartram's and the Meantime Fans’ Bar will both be open from 3pm.
