Ouch, really nasty looking collision in the Brum game, Ibanez getting a massive whack in the side of the head, looked out before he hit the ground though not quite the impact/type of smash into the ground as Drogba. One of the Brum players, having seen the guy while they were treating him, was crying, clearly very upset, hope its not as bad as it seems like it might be.
As for Townsend, the guy deserved to get sent off, simple as that, second yellow, he missed the tackle and pulled him back, thats a second yellow right there, what the player does afterwards is irrelevant, dive, or stands up, the pull is what the yellow card should have been for.
Dive, he went down kind of easy but then the way you go down often looks rather silly when two people are pulling in opposite directions and one lets go
Also, in fairness the ref should have seen the replays of his truly awful sending off, and as most ref's do try to even it up, considering the guy actually did a blatant yellow card offense its even more ridiculous he didn't send him off. The ref has been abysmal.
