Celtic secured a dramatic penalty shoot-out victory over Rangers in the Scottish Cup quarter-final, advancing to the semi-finals despite failing to register a shot on target in 120 minutes. Tomas Cvancara netted the decisive spot-kick, ending a tense Old Firm clash that saw crowd trouble mar the occasion.

Fans from both clubs spilled onto the pitch at full-time, launching missiles at one another as police intervened. This marked the first time travelling supporters had been granted the traditional away allocation of 7,500 tickets in eight years. The violence overshadowed what was already a cagey affair between the Glasgow rivals.

With league leaders Hearts, cup holders Aberdeen, and fellow top-six sides Motherwell and Hibernian already eliminated, Martin O'Neill's Celtic now enter the semi-finals as red-hot favourites to lift the trophy. Rangers, meanwhile, find themselves out of both domestic cups and European competition, leaving the league title as their only remaining chance for silverware this season.
