Celtic boss Neil Lennon has confirmed that Kris Commons will miss Tuesday's Champions League clash against Ajax through injury.
The Scottish international forward has recently been struggling with a hamstring strain.
However, Commons is likely to return for Sunday's trip to Partick Thistle in the Scottish Premiership.
"We are hoping it's not as bad as a tear but he will be out for tomorrow," Lennon told reporters.
Celtic go into the match at Parkhead at the bottom of Group H after suffering two defeats from their opening two fixtures.
