Godolphin's St Leger winner Encke is poised to return to action in the Glorious Stakes at Goodwood after pleasing connections in a racecourse gallop at Newmarket.
Not seen since denying Camelot a place in history in 2012, Encke was suspended from racing for the majority of last year following the Mahmood Al Zarooni drugs scandal.
Encke worked with Personal Opinion over a mile and drew clear with two furlongs to run.
"Encke came out of the gallop very well this morning and it is all systems go for Goodwood at the moment," trainer Charlie Appleby said on Godolphin's website.
"He is heading for the Group Three Coutts Glorious Stakes over a mile and a half on Friday, August 1, provided there is good ground. We wouldn't want to race him on fast ground there.
"Encke is showing all the right signs but the race will tell us whether he holds the same enthusiasm and ability he displayed as a three-year-old.
"He was in Dubai for the winter and we have taken our time with him on purpose so he can compete in the second half of this season."
