Ireland's Paul McGinley is the latest of Europe's Ryder Cup heroes to feel the effects of their record-equalling triumph.
McGinley will compete in the Alfred Dunhill Links Championship in Scotland starting today despite suffering from a bad case of the flu which curtailed his K Club celebrations.
"I was in bed for four days after the Ryder Cup," said McGinley, who sportingly conceded a half to J J Henry in the singles as Ian Woosnam's side cruised to an historic third successive victory.
"It seems like all our systems are run down as quite a few of us have been since, but I'm all right and need to try to salvage something from the end of the season and move up the Order of Merit (he is 68th).
"It was disappointing not to play at The Grove last week but I have no excuses.
"I've had a poor season and fell out of the world's top 50 so didn't qualify."
Luke Donald and Sergio Garcia are the only members of the team not playing at St Andrews, Carnoustie and Kingsbarns, where the focus will be on the battle to win the Order of Merit.
Paul Casey has an £80,000 lead over Ryder Cup teammate David Howell with three events remaining but fellow team members Robert Karlsson (third), Henrik Stenson (fourth), Padraig Harrington (fifth) and Colin Montgomerie (seventh) have a chance to top the standings. The first prize this week is £427,000.
Howell is again struggling with a shoulder injury while Casey finished 56th out of 62 last week and said his winning effort in the World Matchplay at Wentworth and the Ryder Cup had taken its toll.
The world No 17 said: "I was toast, I'd run out of energy and had nothing to give last week."
Lee Westwood was also struck down with a recurrence of tonsillitis on the final day at the K Club while Stenson says he has been worn out talking about holing the winning putt 11 days ago.
"It has been pretty hectic, holing the winning putt has meant a lot more interviews," the Swede said.
"The Ryder Cup was a tiring week.
"There was a lot going on in the run-up and then there's the tension; you take a lot out of yourself when you are playing.
"Last week I was a bit tired and I've not done much running up to this event.
"I've not made that much of a deal about the putt because we would have won with or without it, but I guess it's a nice little bonus that it will run on television a few hundred times."
As for his chances of winning the money-list, Stenson added: "If I want to have a sniff at winning it then I need to have a really good week.
"I've done well here in the past with one third and one sixth place so I'm hoping to come up with something similar.
