English golfer Ian Poulter has been named one of Europe's vice-captains for the Ryder Cup after being ruled out of the tournament with injury.

Poulter's announced he'll be out of golf for four months with arthritic problems in his right foot.

He joins already named vice-captains Thomas Bjorn, Paul Lawrie and Padraig Harrington.

Darren Clarke is skipper for the tournament starting in late September.
