Wests Tigers' backrower Simon Dwyer has been cleared of serious injury after being taken to hospital during Friday's NRL clash with Canterbury at Campbelltown.

Dwyer was hardly able to stand up straight after the incident early in the first half when he mistimed a tackle on Bulldogs' prop Michael Hodgson, but Tigers' chief executive Stephen Humphreys defended the medics' decision to let the 22-year-old walk off the field.

"I was concerned as anyone at the look of Simon walking off," Humphreys told Triple M's Dead Set Legends show on Saturday.

"Simon was complaining of a shoulder injury. The trainer immediately called for the doctor.

"Simon was presenting as if he had a fracture or a dislocation of the shoulder. His neck was fine. There was no complaint of any other injury. He wasn't presenting as being concussed. He was quite alert.

"It was quite obvious he was rubbery-legged. That was a result of periphery nerve damage from the impact, which extended down to his leg. As I understand, that's not uncommon to get some spasms there and some very temporary lack of control."

Humphreys also refuted suggestions Dwyer should have been taken from the playing area on a stretcher.

"It's highly unusual to stretcher a player off for a shoulder injury," Humphreys said.

"He's had a series of scans overnight and I'm pleased to say he's been cleared of any serious injury.

"We're waiting for a further scan for the extent of the shoulder injury."
