BRISBANE has been dealt a huge blow just hours before its semi-final against Melbourne with Joe Daniher set to miss the match.

Daniher's partner has gone into labour to give birth to the couple's first child, and the star forward is returning to Brisbane to be by her side for the birth.

The Lions have named Tom Fullarton as his replacement, while young forward Kai Lohmann has been added as an emergency. 

Daniher has had a rollercoaster 2022, missing six weeks in the middle of the year with a shoulder injury and kicking 39 goals from 18 games.

He kicked the match-winner in last Thursday night's elimination final win over Richmond, scrambling the ball through from the goalsquare with 60 seconds remaining to put the Lions into a semi-final.

Daniher's situation is reminiscent of former dual premiership Lion Daniel Bradshaw, who missed the 2000 semi-final loss to Carlton under similar circumstances.

Brisbane has now made five changes all-up to the team that beat the Tigers, with Cam Rayner, Noah Answerth, Darcy Fort and Callum Ah Chee all new to the 22.
