A sore foot could keep Atomic Rain from taking on BlackBerry Preakness (gr. I) winner Rachel Alexandra and Belmont Stakes (gr. I) winner Summer Bird in the Aug. 2 Haskell Invitational (gr. I) at Monmouth Park.

Sheikh Mohammed's Godolphin Stable, which bought the colt from George and Lori Hall last week, is expected to make a decision on Atomic Rain the morning of July 30.

Already on the grounds at Monmouth Park are Summer Bird  ; Arkansas Derby (gr. II) winner Papa Clem  ; Continental Mile stakes winner Bunker Hill; and Iowa Derby winner Duke of Mischief.

Rachel Alexandra is scheduled to arrive the morning of July 31 from Saratoga.

Munnings   will be shipped from Belmont Park the day of the race.
