Two MLS teams against two Mexican teams and NO TV coverage??? Something is inherently wrong with that.
There's been some tape delay on Telemundo. No live games yet, but there has been some tape delay coverage. Telemundo has carried at least three games involving MFL v Central American teams on 3-4 days' tape-delay on Sat or Sun afternoons. They haven't listed these games very far in advance, so it's probably advisable to check listings on Sat morning. I have no idea if Telemundo intends to carry any more games on weekend afternoons, but that's where and when the games have been so far. TV Azteca in Mexico apparently carried the last Morelia v Comunicaciones game, but it doesn't look like Azteca America showed it in the US. That game was actually one of the Telemundo tape delay games (even though TV Azteca and Morelia are affiliated). Also, it's a long shot, but since Necaxa and Televisa are affiliated, it may be useful to keep an eye on the Univision, Telefutura, and Galavision listings. It's doubtful, but who knows.
