SYDNEY has a nervous wait ahead of next week's Opening Round after Taylor Adams hobbled off with a left knee injury in Thursday night's 25-point AAMI Community Series loss to Brisbane.

Adams was caught awkwardly in a Cam Rayner tackle early in the third quarter and went straight to the Swans' dressing-rooms. He was ruled out almost immediately and did not return as the Lions recorded a 12.9 (81) to 8.8 (56) win.

The Swans believes Adams has suffered a mild medial ligament strain, but the full extent of the injury is not yet clear.

Any time on the sidelines would be a big blow for the Swans ahead of facing Melbourne in the season opener at the SCG next Thursday night, with captain Callum Mills (shoulder) and veteran Luke Parker (broken arm) already ruled out.

However, Sydney assistant Jarrad McVeigh was optimistic the midfielder would be cleared to face the Demons.

"He got a knock to his knee so we played that conservatively. He's still clearly a chance for next week," McVeigh said.

Adams, who headed north from Collingwood in the off-season, was in the midst of a strong first-up performance for his new club, having accumulated 15 disposals, including seven clearances, in just over a half.

He was the only injury question mark to come out of a clash that was delayed by 30 minutes after a power outage before the first bounce at Blacktown International Sportspark.

Once play began in the hot and humid conditions – it was in excess of 30 degrees and 70 per cent humidity for much of the night.

Sydney recruit James Jordon was busy, collecting 31 disposals and nine marks, patrolling the wing nicely, while Errol Gulden, who led the Swans for the final pre-season hitout, collected 24 disposals and had a match high nine tackles alongside a goal. Isaac Heeney also hit the score sheet and had 19 disposals of his own. 

Pete Ladhams (18 disposals, three clearances and three tackles) is battling Hayden McLean or Joel Amartey for a spot, and although he'd appear to be slightly behind that duo, did his chances no harm with a strong showing. Sydney had eight individual goal kickers for the match.
