Mercury Hayes ran for touchdowns of 67 and 77 yards in the third quarter to spark the Montreal Alouettes to a 43-33 come-from-behind victory over the Hamilton Tiger-Cats in a CFL preseason game Tuesday.

The crowd of 16,688 at Molson Stadium rose before the game for a standing ovation in tribute of Maurice (Rocket) Richard, the Montreal Canadiens' scoring legend who died May 27.

The defending Grey Cup champion Tiger-Cats took a 14-0 lead in the first quarter on one-yard touchdown runs by quarterback Danny McManus -- last year's Grey Cup and regular-season MVP -- and Ronald Williams, who led the league last year with a team-record 15 touchdowns.

The Alouettes responded in the second quarter with touchdown passes by Anthony Calvillo to running back Thomas Haskins and slot back Alfonzo Browning.

Hamilton led 24-22 lead at halftime, led by McManus's 217 passing yards (11-for-15) over the first two quarters.

Calvillo was 17-for-20 for 256 yards passing before being replaced early in the second half.

It was his first start since inheriting the starting-quarterback job from Tracy Ham, who has retired.

Stanley Jackson replaced Calvillo on Montreal's first drive of the second half and promptly sent Hayes scurrying for a 67-yard, pass-and-run TD -- his first of two in the third quarter.

Jackson also ran for a five-yard touchdown in the fourth as Montreal briefly took a 16-point lead.

The teams played an exhibition overtime to demonstrate new CFL rules.

Under the new format, both teams get a chance to score from the opponent's 35-yard line.

If the teams still have not scored after each side has four attempts, the game is declared a tie.

Hamilton scored a pair of field goals in the demonstration and the Alouettes scored one.
