Barcelona's Lionel Messi got a yellow card during yesterday's draw with Real Sociedad. He started the game on the bench, having just returned from India, where he'd been serving international duty for Argentina.

Real Sociedad drew even so, upon entering the match, Messi tried to draw a PK via jumpy/fally theatrics, thus inspiring ever-whining Real Madrid coach Jose Mourinho to take a veiled shot, and other haters to jerk their "this is why Americans hate soccer" knees.

Embarrassing, sure. But here's what really hurts Barcelona: newly signed forward Alexis Sanchez tore a thigh muscle in the match and will be out 6-to-8 weeks. They'll host AC Milan in their opening UEFA Champions League match on Tuesday.
