Dan McFarland admitted it had been a tough week for Ulster having suffered a first loss to Connacht in Belfast since 1960 on the back of a record loss against Munster in Limerick
Tries from Tiernan O'Halloran and Bundee Aki, along with a penalty try, saw Connacht dramatically beat provincial rivals Ulster 22-15 in the Guinness PRO14 for a first triumph in Belfast in 58 years.
The result saw Ulster fall to their second successive defeat less than week after suffering a record 64-7 reverse at Munster.
Ulster were forced to play the whole of the second half with 14 men on the pitch after flanker Mattie Rea was shown a red card for upending Cian Kelleher just after the restart.
With Marcell Coetzee having been shown a yellow card at the end of the opening 40 minutes, Ulster played the first 10 minutes of the second half with just 13 men which gave them little hope of rescuing the game.
