“He has to take the doctor’s decision seriously because it’s a very important time of the year with the Open coming up,” his manager Stuart Cage said.
Westwood was third in the Open at Turnberry in 2009 and is regarded as one of the favourites to secure his first major title when the Championship begins at St Andrews on 16 July. He was also third at last year’s US PGA Championship and at this year’s Masters went one better, finishing second behind Phil Mickelson.Westwood then won the St Jude Classic before claiming a share of 16th place in the US Open at Pebble Beach. Explaining the background to the injury scare Cage added: “Lee felt pain in the calf and it was swollen on Tuesday. But when he woke this morning his ankle was swollen too so he decided to have it checked out in the physio’s truck.
“The French doctor there thought it could be a blood clot and said Lee should got hospital for tests so he pulled out of the pro-am.”
Ian Poulter was another withdrawal from the pro-am having been troubled by an insect bite that seems to have become infected.
“I was practising at Woburn on Monday and got bitten by a horsefly or something,” the 34-year-old said.
“It was swollen yesterday and when I put my hand in my pocket I felt a big lump on my groin and knew it wasn’t right. I went to the doctors, was given antibiotics and decided I was well enough to fly but that’s probably not done it any good.”
Ryder Cup captain Colin Montgomerie also withdrew from the pre-tournament event, still suffering from the calf strain that has affected him for several weeks.
