The Premier League newcomers have regained the services of their skipper after he injured his foot late last season but he says he is not yet 100% fit.
But Monk insists that he is doing what the club needs as they have some injury worries in the back third but is happy to answer the call if it benefits the Welsh outfit who opened their winning account with a 3-0 home result over West Bromwich Albion on the weekend.
"We all know I'm not 100 per cent, but it is needs must at the moment," Monk told the South Wales Evening Post.
"We've had a difficult couple of weeks with injuries and things so we just have to try to get through it.
"If we had a fully fit squad I have to admit - and I am sure the gaffer will say the same - I probably would not have played last Saturday.
"In an ideal world I would have liked to have had two or three more weeks to recover.
"But things happen and you've got to put the team and the club first."
