Celtic FC has navigated various squad management and disciplinary challenges during early September 2026.

Initially, manager Martin O’Neill addressed injury concerns and lineup selections for a Scottish Premiership match against Aberdeen, noting the return of captain Callum McGregor alongside absences such as Kieran Tierney and Kasper Høgh. 

By mid-September, focus shifted to an upcoming Premier Sports Cup quarter-final against Rangers. While O’Neill confirmed midfielder Mika Baur is available for training, he noted uncertainty regarding the starting goalkeeper and the potential fatigue of forward Camilo Durán. 

The period was also marked by significant disciplinary measures from Police Scotland. Following previous fan disorder and ticket disputes, Celtic fans were barred from attending the match at Ibrox. Furthermore, both Celtic and Rangers were ordered to play their subsequent home Scottish Cup matches behind closed doors and were required to pay £100,000 in compensation to their respective away opponents.
