Glasgow Warriors say they are "entirely happy" with their pitch at Scotstoun Stadium following stinging criticism by Scarlets players.
Scarlets' Wales wing Steff Evans described the 4G surface as "shocking" following last Friday's Guinness PRO14 semi-final between the teams.
His team-mate Johnny McNicholl said the pitch should be "illegal," and Scarlets head coach Wayne Pivac said players had "got a lot of burns, a lot of bad grazing and blisters."
Pivac told BBC Sport that players could not train on Monday ahead of next Saturday's PRO14 final against Leinster in Dublin, with some still sidelined on Tuesday.
"The main thing is to make the burns heal up," Pivac said. "So, no-one trained yesterday in terms of 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.
"I am not sure what other teams have had, we had got a lot of burns, a lot of bad grazing and blisters.
"The surface was very firm. It is what it is, you have got to play on them and you have got to accept it - but I am not a fan."
A Warriors spokesperson said: "Glasgow Warriors are entirely happy with the Scotstoun Stadium pitch, which was only installed in 2016 and is fully compliant with World Rugby's performance specification."
Scarlets won the game 28-13, and Evans criticised the pitch, stating: "These (wounds) are going to be stuck with me for a while. It is a tough field that 4G.
"It was just really dry. The weather didn't help, it was like playing on carpet, it was shocking.
"It's blisters with a bit of pus coming out. You are waking up in bed and the sheets are stuck to your leg about seven times a night. It is not great, you have just got to crack on."
And McNicholl added: "Under foot, it is good when you are running, but as soon as you hit the deck it affects your joints as well.
"I would prefer not to play on them. I remember going down on the deck for the ball and got this massive grass burn on my backside.
"It was like a carpet burn. I said to the trainer straight after with a few words that I felt this pitch should be illegal. I don't like playing on them because they are high risk for injury."
Artificial pitches are in the news in the League of Ireland also, with Oldham not allowing on-loan striker Courtney Duffus line out for Waterford United on Dundalk's Oriel Park pitch on Monday night due to a previous knee injury .
Scarlets' Scotland captain John Barclay, meanwhile, is a doubt for next season's autumn Tests after suffering a ruptured Achilles tendon.
The Scarlets confirmed the extent of back-row forward Barclay's injury after he was hurt during the Glasgow game.
Barclay, who will join Edinburgh this summer following a five-year stint in Wales, has undergone surgery and is expected to be out for around six months.
