Dundee United defender Garry Kenneth did not travel with his team-mates to Poland for the opening leg of their Europa League qualifier.
The centre-half is suffering from a knee injury and was ruled out of the contest after having an X-ray on Tuesday.
Scott Robertson (ankle) and Danny Swanson (back) also miss the trip.
United's numbers were boosted by new signing Gary McKay-Stevens, who is expected to play some part against the Poles.
The match kicks off 3.45pm BST.
Dundee United (squad): Pernis, Dillon, Severin, Dixon, Douglas, Smith, Dow, Watson, Flood, Rankin, Armstrong, McKay-Stevens, Goodwillie, Russell, Daly, Hilson, Banks.
