John Gosden's star grey of last season who went on to land the Group One St Leger at Doncaster suffered a potentially life threatening injury after the flat season had finished and has spent time at Newmarket Equine Hospital during the of season.
The four year old son of Frankel raced five times last season staying unbeaten all the way through the year and now after battling through peritonitis he is back for another season where he will be looking to add another Classic to his roster of accomplishments.
The colt is now thought to have fully recovered from his illness but Gosden will monitor him in the run up to the season and it could see him miss the start of his four year old campaign seeing him later on in the summer.
The condition affects the intestines of the horses which is obviously a massive thing for any living person/animal and they are just thankful that they are able to get the horse back in training for another term.
Logician gave his trainer and owner Prince Khalid Abdullah there fifth St Leger after being a horse that had gone under the radar for most of the season but now back for another year of racing his competition will be fully aware of his capabilities.
(Credit Racing Post) Teddy Grimthorpe, racing manager to Abdullah, said: "Logician was successfully treated for peritonitis which can be a serious condition. I'm pleased to say he's been cleared by the vets and is now back with John Gosden. There's nothing to suggest that this is ongoing and basically you're either clear of it, or you're not."
He added: "There seemed to be no obvious reason for it and he seems fine now. Obviously he'll be a little behind schedule but he was unraced as a two-year-old and in normal circumstances I doubt John would've been in a great hurry with him anyway.
"We'll play it by ear but going forward I don't have anything but normal concerns about him. I suppose if he was ever going to get these things winter is the ideal time."
Grimthorpe added about the horses return date to the track: "I hate putting dates on these things as it's early days but I doubt he'd be out until June or July."
