Toronto FC gave up a two-goal lead for the second straight game as Chris Tierney scored in second half stoppage time to complete a New England Revolution comeback and force a 2-2 draw on Saturday at BMO Field.

The Revolution (5-7-3) scored twice in the final 20 minutes with a goal by Blake Brettschneider and then Tierney's equalizer on virtually the last play of the game.

First-half goals from Danny Koevermans and Ryan Johnson had given TFC (1-10-2) a 2-0 lead at the half, but saw it all come undone much the same way they conceded two late goals to the Houston Dynamo in Wednesday's 3-3 draw.

Both Toronto goals came from headers inside the 18-yard box on pinpoint crosses from the left side by defender and Canadian international Ashtone Morgan.

The result leaves new Toronto head coach Paul Mariner without a win in three games since taking over coaching duties from Aron Winter.

It was dream start for Toronto as Morgan's left sided cross was perfectly met by Koevermans, who muscled out New England defender A.J. Soares to flick the ball into the goal three minutes in.

It was almost an identical delivery from Morgan that created Toronto's second goal right before halftime.

Once again a well-delivered cross from Morgan went to the right place in the New England penalty area. This time, however, Koevermans missed the header but an unmarked Johnson had the wide-open net to head into from about six yards out.

Right before the half, Milos Kocic looked sharp when he dove to his left to push away a header from Revolution defender Stephen McCarthy.

Kocic was eventually undone in the 71st minute when, after diving to his right to parry a Revolution shot from outside the 18-yard box, he was left helpless as substitute Brettschneider picked up the rebound and slotted the ball in.

New England continued to press but it looked as though Toronto would escape with the victory. However, when Florian Lechner crossed the ball in from the right side into a crowded TFC penalty area, Tierney got a head to it and the Toronto players and fans were left stunned. The game ended seconds after play resumed.

Luis Silva, who was one of three TFC players arrested in Houston prior to the draw with the Dynamo, was a second half substitute for Toronto.
