Team captain Darren Clarke previously named Padraig Harrington, Thomas Bjorn and Paul Lawrie as vice-captains
Ian Poulter becomes the latest Ryder Cup vice-captain to be named by team captain Darren Clarke.
Poulter, 40, ruled himself out of playing at the event after admitting he has been dealing with an arthritic joint in his right foot for over two years and is trying to treat the problem.
The English golfer ruled himself out of action for about four months but will join Padraig Harrington, Thomas Bjorn and Paul Lawrie as vice-captains for the biennial event this year held in Minnesota.
"When it became clear, given my current foot condition, that I would not be in a position to try and qualify for the team for a sixth time this year or indeed be able to justify a wildcard pick, I was truly honoured and delighted to be asked by Darren to be a vice-captain," Poulter said in a statement.
"Darren knows I will be there to assist him and the 12 players who will line up at Hazeltine in any way I can."
