A glass bottle was thrown in the direction of Celtic goalkeeper Joe Hart during Old Firm Derby against Rangers.
Officials were forced to clear glass from the Celtic goalmouth after Hart pointed out the broken glass on the pitch. Play was paused after the incident, which happened as both teams were returning to the pitch for the start of the second half. Celtic were leading 2-1 at the time, with Tom Rogic and Cameron Carter-Vickers on target after Aaron Ramsey opened the scoring for Rangers.
The game eventually resumed once the glass was cleared from the penalty area, with Hart himself helping with the process. Fans were quick to condemn the actions on social media.
