Lions forward Allen Christensen will not return to his side’s clash with North Melbourne after copping a massive knock to the head in the first quarter.

The former Cat has played all 10 games for Brisbane this season and been in hot form of late, coming off a season-high 27 disposals against the Swans last week.

Chistensen failed a concussion test and was consequently ruled out for the rest of the game.

Other injuries to Hugh McCluggage (Achilles) and Charlie Cameron (foot) have reduced the Lions to having just one player on their interchange.
