Grant was released at around 10.30am (AEDT) on crutches and was going home for a sleep, a Western Bulldogs spokeswoman said.
The first-year player was one of a group of Bulldogs wading through the water during a recovery session when he was stung on the back of his leg, suffering a small puncture wound. His teammates immediately called an ambulance.
He was treated at the scene and was then admitted to The Alfred hospital as a precautionary measure where he was given morphine for pain.
A club spokeswoman said Grant has been seen by club doctors, however the wound is relatively superficial and he is expected to return to training next week if the wound does not become infected.
Grant told westernbulldogs.com.au that he was surprised by the stingray attack as it had still been quite dark at the time and he didn’t see the stingray.
"One of the other guys said to me they saw it swim off so that was when I realised it might be more serious than I had previously thought. When I saw that I was bleeding I was worried about the poison getting into my body,” he said.
He was named in the squad to play Essendon at Telstra Dome tonight, but will now miss the match. Western Bulldogs Development Manager, Brad Gotch, said the youngster was disappointed to be involved in such an incident on the day of his first potential game in the AFL.
“He had been named in the squad for tonight’s match however several of the other players trained well yesterday so he was advised that he wasn’t likely to play. Even so it’s disappointing for him to now also miss the Williamstown practice match on Saturday,” Gotch told westernbulldogs.com.au.
Grant, who played for the Dandenong Stingrays last year, was taken with the fifth pick in the 2007 NAB AFL Draft.
