Canterbury Bulldogs have secured Ben Hannant with the Broncos and Maroons State of Origin prop agreeing to a three-year deal.

Hannant, 23, made his debut for the Roosters in 2005 before joining the Broncos premiership-winning side in 2006.

With the Bulldogs losing forwards Willie Mason, Mark O'Meley and Nate Myles in recent times, Hannant's decision to move south is viewed as a major boost for the western Sydney club.

The Bulldogs have recently signed Dragons centre Josh Morris and Sharks halfback Brett Kimmorley.

In other news, the Manly Sea Eagles today announced the signing of Parramatta Eels centre and 'boom under 20's star' Tony Williams.

Described by Manly's recruitment manager Noel Cleal as a "Frank Pritchard" type player and a future star of the NRL, Tony Williams has agreed to a three year contract with the northern Sydney club.

"This kid is all power and an explosive player who can play centre but is probably going to make his mark as a back rower playing on the edge as he matures," Cleal said.
