It is the second time Brett Morris has been injured playing on Manly's home ground and the former Test winger wishes he didn't have to ever play there again.

During Saturday's Manly-Roosters round two game at Lottoland, Morris' left knee shifted in some loose turf under the pressure of a regular tackle. He left the field and didn't return for the second half.

A torrential downpour happened before half-time but Morris said he inspected the ground in the warm-up and found it loose in patches.

The 32-year-old has damaged his medial ligament and is facing two to three weeks out. That makes him angry.

"I'd be lying if I said I wasn't," Morris said on Monday after his first session with the Roosters medicos and rehab staff.

"If it was the first time that happened to me I'd probably brush it off.

"But I've been to Brookvale twice now and my knee has dug in and I've had an injury as a result," he said of the 2015 round three game for the Bulldogs against Manly.

"And the first time I did it, it wasn't raining.

"Don't get me wrong, I love playing at suburban grounds – I'm a country boy and I love that sort of stuff. But it's frustrating that this happens because of the surface."

But he could not go as far as banning Brookvale since it was his job to play where his club was scheduled to.

"But there will certainly be a bit of worry if I have to play there again," Morris said.

"We had rain at the SCG in our first round and I didn't see anyone's knees digging that deep [into the turf].

"It is disappointing, frustrating. Obviously a big pre-season, new club, just wanted to get a few games under the belt and start playing some good footy."

He did that with a two-try haul in the World Club Challenge win over Wigan. He had also scored his first NRL try for the Roosters early in the first half before he was injured.

Teammate Isaac Liu said the Lottoland surface was a bit tricky.

"You can definitely feel that's really heavy and definitely slows you down. You can't really get that 100 per cent performance out there," he said.

Manly CEO Lyall Gorman defended the ground and said an independent report in May last year looked at every aspect of the surface and gave it the thumbs up.

"To be pragmatic, when you get conditions like [Saturday] night, anything is possible," Gorman told weekend radio.

NRL head of football Graham Annesley says the surface will be inspected "as soon as possible" and talks with the Sea Eagles and Northern Beaches Council will take place. It is the council that owns and maintains the ground.

The next NRL game at the ground is Manly's round four match against the Rabbitohs on April 6.
