Brown will get the chance to compete for silverware just four days after Celtic were defeated by arch-rivals Rangers on penalties in the semi-final of the Scottish Cup at Hampden.
After the pulsating clash was tied at 2-2 following extra-time, Brown was one of three Celtic players that failed to convert from 12 yards in a 5-4 penalty defeat.
Scotland skipper Brown has urged quiz teams to dig deep to secure his services at tonight’s quiz at the Ghillie Dhu in Edinburgh.
The former Hibs player said: “Please donate as much as you can to the Ultimate Sports Quiz, it’s a great opportunity to have a bit of banter and you can have the chance to get your hands on a trophy.
“If you want me as your eleventh man, I’m not going to offer a great deal but I’ll come along for a little bit of banter and hopefully answer a few more questions than Mickey Stewart as well.
“Please donate as much as you can to the sick kids charity, it means so much to everyone.”
Retired midfielder Stewart, who now works as a football pundit for the BBC, said: “We want to be raising as much money as possible at the Ultimate Sports quiz and I want you to be bidding for me.
“I could be the eleventh man on the team. I get paid to watch football now so I’m meant to know what I’m talking about.
“If anybody ends up paying a penny more for Scott Brown than they do for me then there’s going to be problems and I might just go home. Lets get as much money raised as possible for this great charity.”
Former Scotland and British Lions captain Hastings added: “I am going to be the eleventh man and whoever bids for me I’m guaranteed to get all your rugby questions right and guaranteed to get all your golf questions right.
“I know loads about curling, I know loads about tiddlywinks, snooker, pool and I’m a UFC fan as well. Bid a lot of money, it’s going to a great cause.”
“It’s a massive year for the charity, we have the new Sick Kids hospital being built in Edinburgh and we’re trying to raise an additional £2.9 million to ensure the hospital is a welcoming and friendly environment for kids.
“We want to give the hospital a soul by doing things like putting up interactive walls with games and building a 120-seater cinema in the main concourse.”
