Scarlets say preparations for Saturday’s Pro14 final against Leinster have been hampered by burns and blisters suffered by players in Friday’s semi-final victory at Glasgow.
Coach Wayne Pivac said Scotstoun’s 4G pitch was “very bad”, Steff Evans said it was “shocking” and Johnny McNicholl says such surfaces should be “illegal”.
Pivac said players suffered blisters, sore feet and “a lot of bad burns”.
He added: “No-one trained yesterday in terms of any rugby work on the field and there will be some who won’t train today which is unfortunate, but we will have a full training session on Thursday.
“It’s things that won’t stop them playing, but it’s not ideal.”
Glasgow said they are “entirely happy with” the playing surface.
The Warriors added the pitch “is fully compliant with World Rugby’s performance specification”.
