Warrington Wolves veteran Ben Westwood has announced his plan to retire at the end of the season.

The 38-year-old, who won 27 England caps and featured in two World Cups, is in his 18th campaign with the Wolves, for whom he has made 441 appearances.

In that time, second-row forward Westwood enjoyed outings in five Challenge Cup finals and three Grand Finals, while also scoring 128 tries and kicking 83 goals.

"It's been a difficult decision but one that had to be made. I think the time is right," Westwood, who joined from Wakefield in 2002, told the club's official website.

"I've achieved what I wanted to in the game and 21 years is a long time to play a contact sport like we do.

"I've loved every single minute of it and have achieved some amazing things with some amazing people."
