It remains uncertain whether O'Neill will be well enough to take his place in the dugout for the upcoming fixtures. Celtic have yet to provide any formal clarification on who will lead the team if O'Neill is advised by medical staff to rest at home rather than travel.
While the club have assured supporters that O'Neill should be discharged within a day or two, returning to the high-pressure environment of football management immediately might not be feasible. The coaching staff at Celtic will likely be preparing to take on extra responsibilities during training sessions this week to ensure the squad remains fully focused amid the unexpected absence.
