'Big Brother' housemates Derek, Roberto and Sam have all been nominated for this week's eviction.
Derek and fiery Italian Roberto were disadvantaged after being banned from casting their nominations yesterday.
The two were punished, with hairdresser Craig, for discussing
nominations and plotting to get rid of promotions girl Saskia.
Sam, 23, is also up for the chop after getting the same number of nominations as Derek.
Six housemates voted to put Roberto up for the public vote - Kemal, Makosi, Maxwell, Sam, Saskia and Vanessa.
Sam and Derek both had three nominations, with Sam getting the vote from Anthony, Maxwell, and Vanessa, and Derek being nominated by Anthony, Makosi and Saskia.
Maxwell had two nominations, and Saskia and Science had one each.
Derek is the 4-6 odds-on favourite for the boot on Friday, with Sam at 6-4 and Roberto at 7-1.
