Roger Varian has revealed Sakheer is being investigated for “front limb lameness” following his disappointing run at Royal Ascot last week.

The Zoffany colt won two of his three juvenile starts last season, including the Group Two Mill Reef Stakes at Newbury, and seemingly failed to stay a mile on his reappearance in the 2000 Guineas.

Dropping back to six furlongs, hopes were high ahead of Friday’s Commonwealth Cup, but Sakheer trailed home last of 13 runners.

Varian believes he may have unearthed a valid excuse for that disheartening display, though, posting on Twitter: “Unfortunately Sakheer is not 100 per cent following his run in the Commonwealth Cup at Royal Ascot on Friday.

“He is currently unsound and being investigated for a front limb lameness. He will require a period of time out of training but will return to the track later in the year.

“Whilst this is obviously disappointing, it does go some way to explaining his below-par performance.”
