Declaration Of War has jumped to a prominent position in the betting for Saturday's Coral-Eclipse at Sandown after owners Coolmore suggested the colt was a "possible" runner.
The sponsors introduced the Queen Anne Stakes winner as the 7-2 second favourite behind the 15-8 chance Al Kazeem.
Only Mars appears a guaranteed starter for Aidan O'Brien ahead of Thursday's confirmations, with the sole three-year-old in the field running a career-best race to take third behind Dawn Approach in the St James's Palace Stakes.
But Declaration Of War, who was impressive over a mile in Berkshire, has already won over similar trips to the 10 furlongs including a Group Three last October.
An update on Coolmore's website said: "Currently Mars is a probable runner in the Eclipse Stakes on Saturday, Declaration Of War is also a possible for the race.
"At the moment Camelot is unlikely to run, he hasn't really been himself this season and is going on the easy list for the rest of the month."
