New signing Laurens De Bock – brought in from Club Brugge for a £1.5m fee on Thursday – failed to feature at Portman Road having returned to Belgium in the aftermath of his transfer but the left-back is due to train this week and put himself in contention for Saturday’s clash with Millwall.
“He just faced him, there is contact and it is provocation. He (Knudsen) went for that, he got that and the referee fell into that.”
The match also came at the cost of a first-half injury to winger Pawel Cibicki, a fresh concern for Christiansen who was already without Saiz, Luke Ayling, Matthew Pennington, Ronaldo Vieira, Caleb Ekuban and Cameron Borthwick-Jackson through injury, illness or suspension.
“My son also saw it and I trust my son. From the point of view of where the camera is, there’s no sign of him doing it and I take my conclusion from what I saw, not from what someone said.”
Ronaldo Vieira could also make a timely return from a leg injury as Christiansen ponders multiple selection issues ahead of the weekend.
O’Kane brought down Connolly as the Ipswich midfielder shielded possession for a goal-kick, prompting Knudsen to confront him a few yards from referee Robert Jones.
