PROMISING Sydney forward Tom McCartin will undergo further medical tests next week as he struggles to shake off the effects of a head knock he received a fortnight ago.
McCartin, 19, suffered concussion in a training mishap and has since been on restricted duties.
A news report suggested there were fears the injury was so serious it could jeopardise the young key forward's season and potentially even his career, but the Swans rejected that assertion and hope to have a clearer timeframe for McCartin's recovery after he receives more examinations in coming days.

The lean teenager didn't play in Sydney's practice match against crosstown rivals Greater Western Sydney on Friday morning, but he attended the game along with other teammates who are also on modified programs.
McCartin's older brother Paddy – the St Kilda forward who was the No. 1 pick in the 2014 NAB AFL Draft – has also endured concussion issues in recent times.
The younger McCartin impressively played 15 of the Swans' last 16 games, including a final, in his debut season last year.
Most notably, he kicked a matchwinning dribble goal against eventual grand finallist Collingwood at the SCG in round 20 to lift the Swans back into the top eight.
Last September, the former Geelong Falcons under-18s star signed a two-year contract extension that ties him to the Swans until 2021.
