Celtic wait on Mjallby for Old Firm tie

Johan Mjallby is Celtic’s biggest concern ahead of tomorrow’s Old Firm showdown at Parkhead.

The Sweden international defender suffered a knee injury in training this week and is struggling to be fit.

Bobby Petta is unavailable after moving on loan to Fulham but Didier Agathe and Paul Lambert are pushing for places after recovering from recent injury problems.

Provisional squad: Douglas, Mjallby, Kennedy, Balde, Varga, Miller, Lennon, Maloney, Smith, Petrov, Thompson, Larsson, Sutton, Marshall, Lambert, Wallace, Crainey, Beattie, Laursen, Guppy, Marshall, Hedman, Hartson, Agathe, McNamara.
