London - Argentine centre Juan Martin Hernandez will replace the injured Maxime Mermoz in the Toulon side to face Clermont Auvergne in the all-French European Champions Cup final at Twickenham on Saturday.
Hernandez, 32, played in the Stade Francais side who lost to Toulouse in the 2005 European Cup final.
Australian Matt Giteau will start at flyhalf with Frederic Michalak dropping to the replacements' bench as Toulon bid to win the trophy for the third year in a row.
