BRISBANE Lions midfielder Dayne Beams appears likely to make first appearance of the season against Port Adelaide in round seven.

It was initially hoped Beams might get up for this Sunday's home match against the Sydney Swans, but the club is keen for the reigning best and fairest winner to get some more conditioning.

After overcoming an off-season shoulder reconstruction, Beams has been dogged by knee tendinitis post-Christmas that has prevented him from playing thus far.

But he is now running trouble-free and on the verge on returning.

"The only reason we need to push him back another week is just to get in that extra conditioning he's missed, but he's going along well," Lions football manager Matt Francis said.

"Another week will do him the world of good."

The news is also positive for Allen Christensen, who has passed his first concussion test this week after being knocked out against the Western Bulldogs on Saturday night.

He will increase his physical activity during the week in the hope of being right to play the Swans.

Small forward Josh Green (chest) is "doubtful", while running defender Tom Cutler will be unavailable after dislocating his shoulder.

The Lions are talking to specialists about the best course of action for the 21-year-old, but Francis says the most conservative treatment would have Cutler back in six weeks.
