Senegal broke quickly after intercepting a poor Great Britain corner, and Konate did well to reach a throughball from Pepe Souare and chip it over the onrushing Britain goalkeeper.
Toulouse moved the ball swiftly through several pairs of hands before a Fritz chip enabled Maxime Medard to put Heymans in for an unconverted try, but it was Glasgow who finished the half as they had begun, with a Jackson penalty.
Johne Murphy went close to scoring a Munster try before the break but the ball just beat him to touch after he had hacked on a chipthrough from Tomas O'Leary.
