Brumbies lock Mark Chisholm has penned a two-year deal with French Top 14 side Bayonne starting next season.

The 29-year-old Wallaby, capped 13 times and likely to go to the World Cup later this year, signed a the contract with the option of an extra year with Bayonne, who just missed out on the title play-offs this season.

Chisholm is the fourth big-name acquisition for next season made by Bayonne.

He joins former All Black internationals Sione Lauaki, who signed a three-year contract from French champions Clermont, and Neemia Tialata, who put pen to paper on a two-year deal from Super Rugby outfit Wellington Hurricanes.

Veteran France international utility back Cedric Heymans, who was named in the 32-man squad for the World Cup last week, has also signed from Toulouse.

However, Bayonne manager Christian Gajana said they had terminated talks with Heymans' Toulouse team-mate Frederic Michalak, the mercurially gifted former France fly-half/scrum-half.
