Accam (in) - Wahlstedt (out) (Helsingborg)
Attacking change for the hosts: defender Erik Wahlstedt is replaced by midfielder David Accam.

The referee blows for half-time.
Kris Common's early strike separates the sides at the Olympia stadium. The home side grew in stature as the half wore on, however, and will be keen to turn things around after the break.

Mulgrew (Celtic) is booked.
The Celtic defender is booked for a challenge on Nikola Djurdic.
