Young star Isaac Heeney was rested from the second half of Saturday's win over Port Adelaide as a precaution after his knee tendinitis flared up.

The exciting forward took no part in the contest after the main break as the Swans chose to rest their star youngster.

Heeney also copped a poke in the eye in the first term but stand-in coach Jarrad McVeigh said he took him off as a precaution. 

"Being the first game of the year and (having) a week off we just thought we'd put him on ice for the rest of the game," McVeigh said.

"He's fine, obviously he's a player that wants to be out there all the time that’s just the nature of the game, but he understands that at his age with the tendonitis, he has be smart with it.

"It's not a necessity to play all the NAB Challenge games anyway."

The Swans received no other significant injuries from the contest against the Power and will have a weekend off before their next NAB Challenge match.
