Rob Howley will undergo wrist surgery in the off-season

The former Wales and Lions scrum-half has missed several contact training sessions because of the problem.

But it will not prevent Howley playing in Wasps' first Heineken Cup final or the Zurich Premiership play-offs.

"The injury has hampered me and it's frustrating that my (right) wrist requires surgery, but it is something that needs to be done," said Howley.

"As a professional sportsman and scrum-half, my hands and wrists are a vital part of my job. If they are not right, then I am not doing my job."

The former Wales skipper has proved a key figure behind Wasps' push for Heineken Cup and Zurich Premiership honours.
