Toulouse - France international scrumhalf Rory Kockott has signed a three-year contract extension with Castres, the French Top 14 club announced on Wednesday.
South African-born Kockott, whose previous contract was due to expire in June 2017, arrived at Castres in 2011 before making his international debut for France in 2014 after qualifying through the three-year residency rule.
The 29-year-old helped Castres to the French title in 2013, with his opportunistic try making the difference as favourites Toulon were beaten 19-14.
But Castres are currently eight points outside the top six as they chase a place in the end-of-season playoffs.
Before joining Castres, Kockott played for the Sharks and Lions in Super Rugby.
Following Castres' French title he was courted by giants Toulon, the reigning three-time European champions, but after initially suggesting he would join the big-spending outfit, Kockott committed to remaining with his current employers.
