Wakaso Mubarek has contracted malaria.
Medical officials at Rubin Kazan are treating the winger with tests being carried out on his team mate’s.
Mubarek was on loan at Celtic last season but after scoring on his debut against Salazburg his season went downhill as Ronny Deila’s side raced away with the SPFL title.
Doctors in the Russian state believe that Mubarek contracted the disease during the close season when he holidayed at home in Ghana.
The footballer is being treated at the Republican Infectious Diseases Hospital in Tatarstan and will be released only after a complete recovery with the government authorities fearing the disease could spread.
Head of sanitary protection of the territory of Tatarstan Rospotrebnadzor, Louise Borisov, said “Doctors are also assessing the daily condition of coaches, physiotherapists and other representatives of the football club who were in contact with Mubarak Wakaso.
“Tropical – this is the most severe form of malaria, but the disease is not transmitted from person to person but we are taking the utmost measures to be on the safe side.”
Wakaso started just eight games for Celtic with his spectacular strike against Salzburg the only goal of his loan spell.
After his scoring debut Deila said: “ African players are different from European players, of course. It’s a different culture but I’ve worked a lot with African players and they need to be loved, like everyone else. I think he will develop.
“It’s good that he’s been in Europe now for many years. Had he come straight from Africa, then I would have been more afraid. It’s also easier to be like that in an attacking rather than a defensive position.
“He’s working hard and tactically he’s been good. He knows the game. He takes cares of himself. He has natural talent there. But he needs time, he has a lot more to come.
“He needs to be quicker and sharper, but that will come when he gets games. He didn’t get back to Scotland from international duty last week until the Friday night, so that’s why he didn’t play against Aberdeen. I hadn’t seen him in training but he trained well this week, so he got the chance against Salzburg. He was very good in the game. It was very nice to see.
“He gives us another weapon in the wide midfield positions. He can eliminate players, get past them and he is good on the ball. That’s what I wanted to see and I’m happy for him.”
Mubarek’s final game for Celtic was as a half-time substitute in the 1-0 home defeat from St Johnstone at the start of March.
