Connections of Fahamore were in trouble with the stewards at Down Royal after officials inquired into the running and riding of the six-year-old in the Irish Stallions Farms European Breeders Fund Beginners Chase.
Held up in the early stages, the Niall Madden-ridden gelding finished fourth, beaten 19 and a half lengths by winner Leish Oscar.
The stewards heard evidence from Madden and trainer Edward Harty, and also received a report from the Turf Club Veterinary Officer who stated that Fahamore was post-race normal.
Having viewed the recording of the race and considered the evidence, the stewards were of the opinion that Harty and Madden were in breach of Rule 212, fining the trainer 1,000 euro and suspending Madden for seven race days, while he was also ordered to forfeit his riding fee.
The JP McManus-owned Fahamore was suspended from running for 42 days.
Elsewhere on the card, McManus's On The Fringe played a starring role in the Albert Bartlett Hunters Chase.
Sidelined by injury since winning at the Punchestown Festival in May of last year, Enda Bolger's talented eight-year-old was a 5-1 shot as he tackled Salsify, dual winner of the Foxhunter Chase at Cheltenham, and his old rival Tammys Hill.
Ireland's two star hunter chasers both performed creditably to fill the places, but On The Fringe came home victorious, scoring comfortably under Nina Carberry.
Tammys Hill (6-4 favourite) was three lengths away in second, four and a quarter lengths in advance of Salsify (3-1) in third.
Bolger said: "He fractured a bone in his hock last year. He's a bit brittle, but is a good horse and his jumping has always been fantastic.
"We'll look at Leopardstown and Cheltenham for him.
"JT (McNamara) rode him (on his last appearance) and said we are going to go places with him.
"He finished fourth in the Foxhunter Chase (in 2011) but he'll be better for it now he's a man."
