Godolphin Group One winners Encke and Certify, the two highest profile horses banned from racing due to the Mahmood Al Zarooni steroid scandal, will return in coming months.

Encke has not been seen since he foiled Camelot's bid to land the Triple Crown in the St Leger at Doncaster in September 2012 and will be aimed at major races in Europe this year.

Certify, winner of the Shadwell Fillies Mile, also in September 2012, is likely to run at the upcoming Dubai World Cup carnival.

Both are in training with Charlie Appleby.

Steeler, third in the 2012 Racing Post Trophy, is entered for a race at Meydan on Thursday.

"We decided recently to continue with some of the horses who did not race last year," racing manager Simon Crisford said on Godolphin's website.

"They include current entries Artigiano and Steeler plus Certify, who will be aimed at the top fillies' contests during the Carnival.

"Encke is also in training and will go for races in Europe later in the year."

Twenty-two Al Zarooni-trained horses were suspended from racing between April and October last year after testing positive to anabolic steroids.

Their former trainer was banned for eight years.
