Asante Kotoko earned a 0-0 draw with ten men against Aduana Stars on Monday.
Aduana saw plenty of the ball but failed to make their dominance count in the final third as the visitors defended with much grit.
Kotoko were reduced to 10 men after midfielder Jackson Owusu got dismissed with his second yellow card of the game after a rather poor tackle in the 72nd minute.
The result means Aduana failed to catch up leaders WAFA SC. The Fire boys remain second with 34 points, two behind the top-placed team who also drew away to Liberty Professionals on matchday 18 of the GHPL.
