HAWTHORN star Jordan Lewis is in doubt for Saturday night's NAB Challenge game against North Melbourne after he had scans on Friday morning.

Lewis wasn't training at the Ricoh Centre, despite it being a light session mostly consisting of goalkicking.

While not revealing the precise nature of the scans, Hawthorn stand-in coach Cameron Bruce said it wasn't a big concern, and doesn't anticipate any problems for Lewis heading into round one against Geelong on Easter Monday.

"It's just management issues and we're expecting that scan to be all clear. That's what happens with some of these players," Bruce said.

"He'll be ready to go (in round one)."

Lewis, 29, played the Hawks' first two games of the pre-season.

Midfielder Will Langford will go into the home and away season without having played a NAB Challenge game. Bruce confirmed reports Langford suffered ropeburn in an incident on a boat. 

"I just know that he had a little burn on the back of his leg, and the cut affected his ability to train. That's all healed up now," he said.

"He'll play tomorrow for Box Hill in a practice game. He's one of those players that would've been disappointed not playing in the finals last year."

Tim O'Brien won't play against the Kangaroos but Bruce said he pulled up sore from the game against Richmond two weeks ago, and it is not necessarily an indication that fellow forward James Sicily is in pole position for a round one spot.  

The Hawks have a spot in the front half to fill, with Jarryd Roughead out for half the season after having a PCL reconstruction.
