Ian Poulter has been forced to pull out of the Byron Nelson Championship due to injury but insists he will be able to take part in the US Open at Chambers Bay in three weeks time.

The 39-year-old Ryder Cup star, who recorded his first PGA Tour top-five finish in five months last week at Colonial, was scheduled to play in Irving, but tweeted: “I will not be competing this week in Texas, I picked up a slight strain in the gym on Monday, so taking precautions and not chancing it.

“I was looking forward to two weeks in a row, playing good golf, so disappointing not to keep that going. Next event will be @usopengolf.”

Jason Day will also not be playing in the Byron Nelson Championship after suffering from dizziness during the pro-am event.

The 27-year-old Australian has enjoyed a solid year, with his highlight coming when he claimed victory at the Farmers Insurance Open in February.

Former Open champion Louis Oosthuizen is also out of the reckoning in Texas because of a neck problem, while there are fears that the tournament could be ruined by the recent bad weather that has hit the area.

There has been nearly 12 inches of rain recorded in the Dallas area in the last month and the recent Crowne Plaza Invitational, which is only 30 miles to the west of the TPC Four Seasons Resort course which hosts this week’s tournament, was badly affected by the weather.

Jordan Spieth is 5.00 to win the Byron Nelson, with Dustin Johnson 10.00.
