Exeter Chiefs sign forwards Jack Yeandle and Alex Brown

Exeter Chiefs have signed Doncaster forwards Alex Brown and Jack Yeandle for the 2012-13 Premiership season.

Exeter-born hooker Yeandle, aged 22, has started six matches and made 13 appearances off the bench since joining Doncaster at the start of this season.

Prop Brown, also 22, is a former Saracens youngster who has started most of Doncaster's games this season.

"I'm very grateful to Doncaster for developing my career," Brown told the Doncaster website.

"It's disappointing to lose two quality players, but I would never begrudge a player moving to the higher level," said Doncaster's director of rugby Brett Davey.

"I would like to take this opportunity to wish them the best of success with Exeter in the Premiership and the future rugby careers."

The duo join Irish international Ian Whitten in moving to Sandy Park this summer.

They Chiefs have also secured prop Hoani Tui and centre Jason Shoemark to new two-year deals in recent weeks.
