There will be one tiebreaker, and possibly two, on Friday at the Tim Hortons Brier Canadian men's curling championship in Winnipeg.

B.C.'s Bob Ursel and Newfoundland/Labrador's Brad Gushue both won their final round-robin games in Draw 16 Thursday afternoon at the MTS Centre to finish the round-robin with 7-4 records, tied for the fourth and final playoff position.

And Manitoba's Kerry Burtnyk could get into that mix, too, if he wins his final round-robin game tonight, against Saskatchewan's Pat Simmons.

B.C. completed a terrific comeback after opening with a 0-3 record, scoring three in the fourth end and hanging on to beat James Grattan of New Brunswick 8-6.

"What a battle all week," said Ursel. "It's been just crazy. We're pretty excited. We lose our first three games, and to come back against this field and make the tiebreaker or playoffs, we couldn't ask for anything more than that."

New Brunswick finished its Brier with a 2-9 record.

Newfoundland/Labrador, meanwhile, got into the tiebreaker with a 7-6 extra-end victory over P.E.I.'s Peter Gallant 7-6. Gallant had a shot at two in the 10th, but his final rock overcurled and he settled for one.

"Another gut check, another one where we just grinded it out and made a lot of shots late in the game, but just dug a hole for ourselves early," said Gushue, who finished second to Ontario's Glenn Howard last year in Hamilton. "Hopefully, we can get that figured out."

The Islanders finished out with a 3-8 record.

In other Draw 16 action, Saskatchewan's Pat Simmons blew a chance to lock up second place and a berth in Friday's Page playoff one-two game, falling 7-6 to Northern Ontario's Eric Harnden. The result left Saskatchewan at 8-2 and needing to beat Manitoba in tonight's last draw of the round-robin to reach the one-two game against Alberta's Kevin Martin (10-0). A loss combined with a win by Ontario's Glenn Howard, who's up against Nova Scotia's Brian Rafuse, would put Ontario in the one-two game.

Manitoba kept its playoff hopes alive with a 7-3 win over Quebec's Jean-Michel Menard, dropping Quebec to 3-7.

The first- and second-place teams at the end of round-robin play Thursday night will meet in the Page playoff one-two game on Friday while the third- and fourth-place teams also will meet Friday (times TBA). The winner of the one-two game will advance directly to Sunday's championship game (6:30 p.m., all times Eastern) on CBC. The loser will play the winner of the three-four game in Saturday's semifinal at 2:30 p.m. on CBC.

Play at the Tim Hortons Brier resumes Thursday at 8 p.m. on TSN.
