What are the possibilities in florida for violating 2 separate 3rd degree felony probation with another arrest?

A friend of mine was on probation for two separate Grand larceny convictions that were running concurrent. They were told by their P.O. that they were being violated for a dirty urine test. Unfortunately for my friend, they were arrested the same day for another 3rd degree felony of retail theft. They are being held no bond pending hearing. Now on a best worse case scenario does this appear to be a mandatory sentence if found guilty of all or is there a remote possibility of some harsher probation. I know it doesn't sound good.
