Sinndar's trainer John Oxx today reported the colt in good shape following his exertions in yesterday's Budweiser Irish Derby.
"He's fine and there are no problems," Oxx said. "He's fresh and well and he ate up last night.
"It's still the plan to give him a break and he won't run until September.
"He'll have a trial for the Arc - that's his objective."
Sinndar had three stablemates with him in the race, including Raypour who made the running until over a furlong out, but Oxx does not believe Sinndar will always need a pacemaker.
"When it is feasible he'd have one in but he didn't have one at Epsom," Oxx added.
"It depends on the race and the individual circumstances."
