The 28-year-old Muslim has not been involved in the club's pre-season fixtures to date as a result of his refusal to wear the club's new Wonga-sponsored shirt because of his religious beliefs.
However, the two parties managed to find a solution, with the help of the Professional Footballers' Association, last week, and the striker is now back in the Magpies fold.
He was not involved in Sunday's 1-0 victory at Blackpool, but manager Alan Pardew has confirmed he will play some part at St Mirren Park.
Pardew told the Chronicle: "Hatem [Ben Arfa], Colo [Fabricio Coloccini], Papiss, Cheick [Tiote]and a few others stayed behind. They will all play at St Mirren, for sure.
"We should have a good side out there for our fans if they want to travel up.
"Papiss has looked really good. We have only had one training day with him as a group, and he's looked really well.
"I'm pleased with that. It's been a difficult time for him, and now we rally round him and support him."
