Sportingbet made a right mess of this, had Anderson down at 13/2 to win and 9/1 to stop Groves which is crazy considering how good Anderson is.
I got a tip about it and went to get some cash on. Money started to pour on Anderson and within a few hours last night he'd dropped to 15/4 to win and 3/1 stoppage (I know, these odds don't make sense lol), i just checked there and they seem to have stopped takin bets.
