'Assaulted' Jesse Ryder making 'significant progress' following gym stint

New Zealand cricketer Jesse Ryder has reportedly made a significant return to fitness and recovery after a gym stint, following an alleged grievous assault on him that had left him in a coma for a few days.

Ryder said on Twitter that he had completed a gym workout in Wellington, although he admitted that he was paying the price for it physically, the Sydney Morning Herald reports.

Ryder had tweeted, 'Back at gym 2day finally pity I almost died. #GottaWork'.

Ryder was admitted to Christchurch hospital over a month back after sustaining serious head injuries in a late-night assault by unidentified men in a bar, and the New Zealand batsman has now been put under intensive care, according to the local police.

According to emerging reports from local media Ryder was attacked twice in quick succession, suffering serious head injuries in the second part of what a witness called a 'Jesse hate fight'.

Two men have been charged over the incident, the report added.
