Brazil - Argentina live blog coming up!

A quick note that I'll be live-blogging tomorrow morning's men's Olympic soccer semifinal between Brazil and Argentina. It should be a great clash of South American superstars, with Ronaldinho and Lionel Messi going head-to-head. Here's an excellent preview of both semifinals (the other, earlier one features Belgium and Nigeria) from ESPN Soccernet's Jeff Carlisle. The Brazil-Argentina match starts at 9 a.m. ET (6 a.m. Pacific). It may be on TSN: they say they're showing one of the semifinals, but don't mention which one. In any case, it will certainly be on CBC's digital streaming coverage (www.cbc.ca/olympics), and it will be here as well, gremlins permitting.
