Don't know if they will, but they should. It was an incredible game. Best of the year, and yes I did see the S.J./L.A. second leg.
fsw usually rebroadcasts one of the mls games on tuesday at 2pm. soccertv.com has it listed as the chicago/new england game, but i wouldn't be surprised if it ended up being the sj/kc game instead. edit - actually it is listed for monday at 4pm central time.
I think it'd be great if they'd rebroadcast both games instead of showing 2 week old premier league games like they're scheduled to do. Both were good games, but I agree San Jose-Kansas City was better.
They already rebroadcasted the SJ/LA game Friday night before the CHI/NE game and rebroadcasted the CHI/NE game before last night's SJ/KC game. That's a doubleheader of MLS on both Friday and Saturday nights though one of the games each night was on tape. My FSW schedule is showing MLS Soccer Monday at 5pm ET right after the EPL game. The teams are TBD but I wouldn't doubt it's SJ/KC since the CHI/NE semi has already been rebroadcast.
