99 in BB with 2 raises against me

[Jackrabbit Slim]

My first thought when I saw my nines was that I'm gonna push these against the probable limpers since the table had been sort of passive. Now the first guy raises but I'm still thinking pushing is a good idea until the SB also calls. Now, with one raise and one call there is a pretty good chance I'm beat or up against at least one coinflip since I most likely can't get both of them to fold with a push. Is a fold here terribly weak/tight?
