Plymouth Albion chairman Graham Dawe felt a 'dubious' penalty try cost his side in the 39-22 defeat at Bristol.
Albion were 17-3 down at half time after George Watkin's try and the penalty score.
Plymouth had hope when Mick McGrath's try got them within 10 points.
But two tries in three minutes from Watkins and Chris Williams killed the game off, despite Albion tries from Bevon Armitage and Wayne Sprangle before Marco Mama's late score.
James Love missed 14 points from kicks to end a tough day for Albion at the Memorial Stadium.
"A dubious penalty try took the stuffing out of us in the first half," Dawe told BBC Radio Devon.
"Bristol took their chances very well, they played with a lot of momentum when they managed to get some phases together," he added.
