A Division A1 semi-final steeped in controversy saw Cambodian Rice Bank stage a walk-off deep into extra time when opponents Tri-Asia Phnom Penh FC were 3-2 up.

The Battambang side had been reduced to 10 men in the 38th minute through a double booking of one of their players, but managed to finish regulation time with the scores locked at 2-2.

Tri-Asia were awarded a penalty in the second half of extra time when the Rice Bank keeper appeared to commit a professional foul.

But his subsequent dismissal caused tempers to boil over as the side refused to see out the full match.

Tri-Asia will face Takeo province, who beat Western University 5-4 via penalties in yesterday’s other semi-final, at 7am tomorrow at the Cher Teal Sports Institute field in the title decider.

The third place play-off will be held today at 7:30am at the same pitch.
