Worcester coach Richard Hill was furious his side lost 29-23 to Gloucester to a last-minute penalty try and also had Errie Claassens sent off.
In a tight Aviva Premiership clash at Kingsholm on Friday night, Claassens was sent off for tripping Jonny May in the dying moments and referee David Rose awarded a penalty try, which was converted, after consulting the Television Match Official.
That final score earned Gloucester a victory which denied Worcester a valuable win in their bid to pull away from the relegation fight at the foot of the table.
Hill said: "It wasn't a penalty try; Paul Hodgson was covering across behind Errie.
Hill also revealed the Worcester full-back was not happy to be penalised for a score which saw Gloucester take the points.
"Errie is distraught and devastated and it's a very cruel way to lose a game," added Hill.
"We came within a whisker of beating them."
But opposite number Nigel Davies was in no doubt that an offence had been committed.
The Gloucester coach said: "Jonny May shouldn't have been tripped.
"I can't say he would definitely have scored but it was definitely a penalty.
"Jonny created chaos, he is an X Factor player and he is excellent when he is put in space."
Despite the defeat, Hill could not fault his players who pushed Gloucester all the way.
"I thought we played some really good rugby. We played with a huge amount of effort and intent," he said.
"Ill discipline did cost with Sam Betty's yellow card and despite talking about it at half-time we still gave away two penalties with minutes of the restart."
Davies was happy with the win but not with his side's performance.
"It's a very tough league and every win is important especially as we had a hard game at Wasps last Sunday and this was a quick turnaround," said Davies.
"We worked hard to give ourselves that late chance and played with a lot of character.
"There were good patterns of play but in the first half our kicking was atrocious.
"We are not the finished article and there is a lot of growth to come," added the Gloucester. coach.
Gloucester's other try came from Henry Trinder, with Rob Cook kicking two conversions and four penalties and Ryan Mills kicking a penalty.
For Worcester Josh Matavesi and Alex Grove touched down and Andy Goode kicked two conversions and two penalties.
