Ian Poulter was so concerned for his young family he had workers exchange all the air conditioining filters in his house in an effort to combat a chest infection.

Poulter and his wife, along with four children, were each struck down by the virus over the past week since last competing in the Arnold Palmer Invitational in Orlando.

And it’s for this reason, Poulter has joined victorious Ryder Cup winning team mate, Rory McIlroy in contesting this week’s Valero Texas Open.

“I’ve got through much of the illness but then I’m still on anti-biotics,” said Poulter.

“I’m about 90% and I’ve got my strength but it’s just that I still feel bits and pieces, so this afternoon in the steam room I should be okay.

“But we had the whole house stripped out in terms of putting new filters in right through the house but that’s what happens when you’ve got four kids as they pick up bugs.

“So as strong as I have been throughout the year, last week was a real kick in the proverbial.”

Unforunately, thunderstorms meant Poulter managed to get to play 11 holes of this week’s TPC San Antonio course after only arriving into the sprawling Texas city on Tuesday evening.

“I’m looking forward to seeing the other seven holes, so I’ve got some idea where I’m going,” said Poulter.

“I’m not sure when I’m going to do that, but I might have to do it later this afternoon.

“I’ll try and walk the course and just visually have a look at those extra holes.

“But apart from that, I think the golf course  will suit my game.  You have to drive it very straight. You have to be pretty accurate, and you’re going to miss some of these greens in the wrong spot and you will have to get up and down.

“But then the yardage books are pretty good nowadays, and it really doesn’t make a difference.  Also Terry, my caddy, will be pretty much my guide and he definitley be go out looking at the course, so if I don’t go out I will be guided by Terry.
