Bulldogs centre and NSW 18th man Jamal Idris will be available for an exclusive live online chat on NRL.com on Thursday from midday.

Idris will review Game 1 of the 2011 Harvey Norman Origin Series and his time in camp with the NSW VB Blues.

He will also preview the Bulldogs' clash with the Titans in the double-header at Brisbane's Suncorp Stadium on Friday night.

The Bulldogs have moved captain Andrew Ryan to prop for the match starting at 8.45pm, following the Broncos and Sea Eagles clash which kicks off at 7pm.

The Broncos have not named three of their Queensland Origin stars - Darren Lockyer, Sam Thaiday and Ben Hannant - for the match.
