Boxing Help

[Midwesterner]

I need to know if I'm missing something obvious with this line. It is after the fight, so I'm just checking the rules for another fight. Jones was -1100 at Bodog, but this props bet looks fishy unless I'm missing something. If I wanted to bet on Jones, then shouldn't I make 2 bets on him by KO and decision in the prop bets. What is the catch?

that is pretty weird. Not very ofter you see something like that. Only thing i can think of is that there was a good chance for him to win by decision or KO. I know the props have limits on them too. you would assume the Jones by decision like should have been around -300, and the KO could have been even
