LACHIE Neale will not feature in the rest of Brisbane's finals campaign after scans revealed a right calf tear that will sideline the dual Brownlow medallist for four to six weeks.

Neale left the field in the final term of Friday night's 38-point loss to Geelong in Melbourne and did not return.

The Lions confirmed the scan results on Saturday afternoon after Neale returned to Brisbane.

It was Neale's first game in more than a month, having been sidelined for the last three games of the home and away season due to a quad complaint.

It comes as forward Eric Hipwood was also ruled out for the year after scans revealed a partial ACL tear.

They join premiership defenders Jack Payne (knee) and Noah Answerth (Achilles) on the sidelines.

After the loss to the Cats, Brisbane's premiership defence is on a knife's edge, with the Lions facing a sudden-death semi-final clash against either Fremantle or Gold Coast on Saturday night at the Gabba.
