Sam Gibson had scans on his back on Monday after hurting it in the dramatic win over Carlton a day earlier, but he has not appeared on the club's injury list. The midfielder's 118 consecutive games are the longest active streak in the AFL. There was concern for Trent Dumont in his first match back, after missing the previous week with concussion, when he suffered another head knock against the Blues, but he passed a concussion test and he and club doctors have declared him ready to go for Saturday night's clash with Richmond. There could be some injury relief for North after its round 12 bye. - Marc McGowan
