Nicho Hynes suffered a syndesmosis injury at training on Monday, and will miss the next 6-8 weeks.
The 28-year-old halfback was assisted from the field by two people, and later seen in a moonboot.
## What happened?
The incident occurred during a training session, with Hynes not placing any weight on his ankle.
He underwent MRI scans, which confirmed the extent of the injury.
Journalist David Riccio described the dressing room as "sombre" after Hynes went down.
## Why it matters for Nicho Hynes
The injury is a significant blow to the Sharks, who have lost five of their last six games.
Hynes' form has come under scrutiny, after being dropped from NSW's State of Origin team.
## What comes next?
Dan Atkinson is likely to fill the void left by Hynes, partnering Braydon Trindall in the halves.
Prop Tom Hazleton expressed concern for his teammate, saying "anyone in the squad, you don’t want to see them getting hurt".
And in a separate incident, Hynes was hailed for stopping a person from committing suicide near Wollongong.
2GB presenter Spiro Christopoulos confirmed the story, saying Hynes told him "Yeah, mate. It happened. Crazy stuff".
Respected NRL journalist Nick Tedeschi praised Hynes, saying "hearing Nicho Hynes did something pretty special today. Well done to the young man".
The Sharks face the Wests Tigers on Friday night, before a bye in Round 20.
Forward Siosifa Talakai will also miss the clash, after accepting a one-game ban for a high tackle.
As the Sharks look to recover from their recent losses, they will have to do so without their star halfback.
The club has gone from first on the ladder to only four points clear of 10th spot.
But despite the injury drama, Hynes' heroic act has earned him praise from the rugby league community.
He has been described as "classy" and a "tough guy" by his teammates and journalists alike.
And as he recovers from his injury, Hynes will be looking to return to the field and help the Sharks turn their season around.
The Sharks will play through until the end of the regular season without another rest, making Hynes' recovery even more crucial.
With the Sharks facing a tough road ahead, they will be hoping Hynes can return to the field soon.
As of Monday, Hynes' injury has been confirmed, and he will begin his road to recovery.
The NRL community has rallied around Hynes, praising his heroic act and wishing him a speedy recovery.
