Speaking ahead of their Pool six clash, Kellock admitted losing Magners League record points scorer Parks was a blow, but was adamant his replacements had sufficient quality to thrive in his absence.
"Dan is a great player and would be a loss to any team. But, saying that, the two young guys at 10 - Ruaridh Jackson and Duncan Weir - are real stars," said Kellock.
"They both have great attitudes and I'm excited about them. But the things that have gone wrong are not down to the guys that have come in, they are team things.
"If we can get that sorted out then I believe we will start to win games."
