The Hoops captain says they are playing through the pain barrier this season.
The Hoops are now one game away from securing the Scottish Premier League title after they beat Aberdeen 3-1 at the weekend.
That result saw Celtic put one hand on the title, with their superior goal difference all but ensuring they will finish top of the table.
It will be their fifth successive title win, Brown’s sixth in total, and it will prove a positive end to what has been a tumultuous season under Ronny Deila, who will depart in the summer.
Brown though, says that some fans do not understand what the players have been going through on the field.
“There have been a lot of injuries and people playing through the pain barrier for the club,” he told celticfc.net. “I think some fans maybe don’t understand that. People only see who turns up on the park and they don’t see the day to day.
“Any of the lads would play through the pain barrier if it means them getting 90 minutes on the park, winning the title or being involved in title-winning games.”
With the title all but confirmed, attention will now turn to who Celtic will name as their next manager.
It is a hugely attractive job for a number of managers, and the list of potential candidates has already begun to grow since Deila announce his departure.
The current idea seems to be that a man with previous association to the club is needed, with the likes of Neil Lennon, Paul Lambert and David Moyes already linked.
