Ronny Deila has yet to decide if he will take Aleksandar Tonev to Aberdeen on Sunday despite appealing the Celtic winger's racism ban
Celtic live updates
John Guidetti returns to the Celtic squad for the trip to Aberdeen in the Scottish Premiership on Sunday.
The Swedish striker, 22, was ineligible for the Hoops' 1-1 Europa League draw with Astra Giurgiu.
Kris Commons (buttock) and James Forrest (hamstring) are back in contention and manager Ronny Deila is hoping Anthony Stokes has recovered from the sore throat which kept him out of the trip to Romania, although winger Derk Boerrigter remains out following knee surgery.
Provisional Celtic squad: Gordon, Lustig, Matthews, Izaguirre, Denayer, Ambrose, Mulgrew, Van Dijk, Kayal, Johansen, Bitton, Brown, Commons, Berget, Scepovic, Wakaso, McGregor, Guidetti, Griffiths, Stokes, Henderson, Zaluska, O'Connell.
Man City loanee John Guidetti celebrates his goal for Celtic, who lead Ross County 4-0 in the SPL after 35 minutes.
Arsenal have been linked with a January swoop for Celtic's beatboxing defender Virgil van Dijk.
Van Dijk, 23, is a Dutch Under-21 international who will surely improve and become a regular for the senior national side.
According to the Daily Telegraph, the Gunners have earmarked a budget of £20m for Arsene Wenger to spend on new players.
We have no idea what J-Guide is rapping about, as our Swedish is very rusty, but his flow is tight. Decent beatboxing from his Celtic team-mate too.
Celtic skipper Scott Brown did not return with the squad after Thursday night's 2-2 draw with Salzburg in Austria as he missed the returning plane to Glasgow due to a routine drugs test.
The Hoops midfielder scored his side's second goal in an enthralling Group D encounter and was picked for the obligatory drugs test after the game.
Celtic had to leave on a designated 2255 flight which meant the Scotland midfielder had to stay behind for the night.
Celtic expect him to return later on Friday ahead of Sunday's Premiership clash against Motherwell at Celtic Park.
