The extent of Bird's injury was not clear just after the game with his right leg packed in ice.
Despite a week of headlines about the club's dire financial state, the players turned on a show for the 14,344 attended the match, well up on their season average of just over 11,000.
Speculation Scott Prince would be a late inclusion at halfback proved on the money.
It was Prince's cross field bomb in the fifth minute which centre Steve Michaels leapt high to knock backwards which led to Bird scoring wide out.
A handling error by Bulldogs hooker Michael Ennis gifted Brenton Lawrence a 40m try and a 10-0 lead before the Bulldogs found their attacking mojo.
Ennis was forced off the field for treatment to a head wound and his replacement Joel Romelo started a move which resulted in Barba scoring to give the visitors a 18-14 lead at the break.
The Titans enjoyed an element of luck with two of Prince's re-starts after Bulldog tries hitting the post and rebounding back into the field of play.
His first direct hit which was gathered up by forward Luke Douglas led to winger Kevin Gordon scoring in the 22nd minute.
Prince's vision saw the Bulldogs' defence was short on the right and he fired a long spiralling pass to Gordon that cut out three teammates.
