Millwall's in-stadia betting partner EnergyBet will once again feature on the sleeve of The Lions' shirts during this Sunday's televised Emirates FA Cup Quarter-Final tie against Brighton & Hove Albion, LIVE on BBC One (kick-off 2pm).
An EnergyBet spokesperson said: "It was great for our brand to be on the sleeve of Millwall's shirt in the 3-2 win over Everton in Fourth Round of the FA Cup. The support of the Millwall fans that evening was superb, and the noise when Murray Wallace scored the winning goal was electric.
"We look forward to appearing on the home kit for this Sunday's match against Brighton and hope to see the same result as last time, with Millwall progressing to the Semi-Final. We look forward to hosting fans at the game and ensuring they have a day to remember."
Stuart Lock, Millwall’s Head of Commercial and Retail, added: "We are proud to once again wear EnergyBet’s logo on the sleeves of our shirts for one of the biggest occasions The Den will have hosted in the past decade and more.
"Our close relationship with EnergyBet, which we believe is of great benefit to Millwall supporters, continues to go from strength to strength and this latest sleeve sponsorship is a continuation of that."
