Woodbridge said Hewitt, 31, had revealed he has no immediate plans to retire.
"In actual fact, quite the opposite of that," he said.
"His schedule is set and he's talking next year.
"He's said people have asked that (retirement) question and he's laughed at them because he's not ready to do that.
"It's certainly not on his radar unless he's given it (retirement date) to himself with what he's planning.
"And I think that's all because his foot is feeling good."
