France international Serge Betsen has signed a one-year contract extension with Guinness Premiership club Wasps.

The former Biarritz flanker joined Wasps in 2008, and his new deal will keep him at Adams Park until at least the end of next season.

Wasps have also announced fresh terms for prop Ben Broster, hooker Joe Ward and flanker Will Matthews, who have all agreed two-year contracts.
