MIKAEL LUSTIG is struggling to make Saturday’s Premiership meeting with Motherwell after injuring a knee on World Cup duty with Sweden.
The 29-year-old right-back scored the only goal of the game against Luxembourg last week, but had to pull out of the 3-0 triumph over Bulgaria on Monday night.
Lustig was due to play again for his nation, but was forced to withdraw just a couple of hours before kick-off.
And now Brendan Rodgers faces a worrying wait before the Hoops medics assess the extent of his injury.
Swedish FA spokesman Niklas Bodell said: “Mikael took a hit to his knee in the game against Luxembourg.
“He felt it in training before the game with Bulgaria and it hurt him when he ran. The medical team tested him before the start and stated he could not play.”
Lustig has featured in all but two of Celtic’s games this season and with key games against Mark McGhee’s Fir Park outfit, Borussia Monchengladbach and Sevco Rangers looming, Rodgers will be hoping he gets the all-clear.
