Speaking to CATV on Friday, Pattinson says he will return to the crease next week ahead of schedule.
"It’s all going pretty well at the moment," said the Victorian quick.
"I had a scan on Tuesday morning and came back all clear, so all the healing part is over now and I can stuck into lifting some heavy weights and start back bowling next week and go from there.
"I got told it would be four weeks after I start running.
"I’ve got my first running session today so I start getting into the exciting stuff, which is good."
