BATH centre Gavin Henson has been named in the Probables squad to prepare for Wales' senior trial match on May 30.

Henson, 32, has not played for Wales since he was injured during a 2011 World Cup warm-up game against England in Cardiff.

Henson is among a 26-man Probables squad that will be captained by Alun-Wyn Jones to face the Possibles, another 26-man group under the leadership of Cardiff Blues hooker Matthew Rees.

The game is a full-blown preparation for Wales' two-Test South Africa tour next month.

Wales head coach Warren Gatland is due to announce a 31-man tour squad during his post-match press conference following the trial game at Swansea's Liberty Stadium.

There is no guarantee, though, that Henson and other Wales players with Aviva Premiership clubs will be released for the trial.

English clubs and French teams are not obliged to release players as the game is not a Test match, as stipulated by the International Rugby Board.

Gatland's assistant and Probables head coach Rob Howley said: "The trial is a great platform for us to see all of these players up close and allow them to pit themselves against each other.

"It takes us back to the traditional Wales trials of old, and gives players an opportunity to put their hand up for the Wales jersey. Both sides will be going hard against each other with players having a point to prove.

"It's also a vital game in our preparation ahead of the tour to South Africa. The vast majority of the squad wouldn't have had any game time after last weekend, and this allows us to have a meaningful match."

Bath prop Paul James is included in the Possibles squad coached by Robin McBryde.
