Boss' left-back problem
Celtic, 18:39, August 25, 2010 ,
Charlie Mulgrew and Cha Du-Ri out of Celtic's Europa League qualifier second leg in Holland on Thursday night.
Hoops boss Neil Lennon is considering former Cardiff City midfielder Joe Ledley for the left-back slot against Utrecht as his side look to secure their place in the group phase of the competition next month.
Israeli winger Beram Kayal impressed in the first leg, which Celtic won 2-0 at Parkhead, but they are without ex-Scunthorpe striker Gary Hooper for a month.
Marc Wilson and Niall McGinn have joined him on the sidelines but Lennon can recall Jos Hooivied after a one-match ban.
Utrecht are a much better side at their 25,000-capacity Stadion Galganwaard and defeated Willem II 3-0 at the weekend with a quickfire brace from Dutch international Ricky van Wolfswinkel and one from Danish midfielder Michael Silberbauer.
