Euro 2012 knock out stages opens Thursday with Portugal vs. Czech Republic. These same two sides met in the quarter finals of Euro 1996 in England, and on that occasion it was the Czech Republic that came out on top in a 1-0 win. This time, however, Portugal will be the favorites in most people's eyes. The match kicks off at 2.45 p.m. and can be watched live on ESPN, or alternatively online through live stream on ESPN3 (details below).
