Tarik Elyounoussi is a major injury doubt ahead AIK's Europa League showdown with Celtic after hobbling off at the weekend.
The Norwegian hitman was suspended for the first leg in Glasgow and had previously written Hoops off after insisting AIK had nothing to be afraid of.
But he was taken off in the first half of their 3-1 weekend win against Ostersund after a calf injury. Now AIK's top scorer will get scans done this week to discover how bad the extent of the injury is.
Like Celtic, the Stockholm club also have a huge city derby at the weekend after the Europa League clash.
They face Djurgardens in a top of the table clash.
Elyounoussi said: "I'm hoping the injury isn't too bad because we have two really important games this week against Celtic and Djurgardens.
"I came off because I didn't want to take any chances and make the injury worse.
"It feels sore now, but I am praying it's not too bad. I will get a scan once it settles down."
Neil Lennon 's made light work of Hearts on Sunday and know an away goal in the Friends Arena will leave AIK needing to score four goals to qualify.
