Celtic have been criticised for the late discovery of Alex Oxlade-Chamberlain’s Champions League suspension.
Former Aberdeen chief executive Keith Wyness called the oversight "due diligence 101" and pointed the finger at chief executive Michael Nicholson.
The 33-year-old midfielder is banned for both legs of the play-off against LASK, beginning Wednesday, and the opening league-phase match if Celtic get through.
The suspension stems from a red card received while playing for Besiktas in 2023. Wyness, speaking to Football Insider, said: "This is simple due diligence 101 that should have been done.
"Certainly somebody’s in a lot of trouble about this."

He believes the issue should have been identified before the former England international's move to Glasgow.
"If they haven’t done that due diligence and understood what’s going on, the club secretary would have been through that with a fine-tooth comb to understand those sorts of issues," he said.
Wyness fears the suspension could be a major talking point if Celtic fail to beat Austrian side LASK. "Especially considering how big European football is for Celtic, you don’t have that sort of mistake happen," he said.
"And so here they are with a self-inflicted wound. If Celtic don’t get through, this will be brought up, believe me, and the fans will throw this right back at the administration’s face.
"And at that stage, maybe heads will roll. In the end, the chief executive will be ultimately responsible for a mistake like this."
