TFC drew 1-1 with Pumas last night, while in a shocker Tauro defeated FC Dallas 5-3 tonight in Panama. With 1 matchday left, Pumas lead the group on 8 points with Dallas and TFC tied at 7 points. TFC's final match will be at Dallas on Oct. 18th.
As I understand the process, the 1st tie-breaker is points in the 2 games between the tied teams, then goal difference in those games followed by away goals. Basically, TFC will need to win in Dallas and score at least 2 goals in the process, as Dallas won the 1st game 1-0.
