The allrounder is “desperate” to contest Friday’s one-day international series-decider in Durban, despite suffering back spasms in game two on Sunday.

And Watson says he still intends to play in next week’s four-day tour match against South Africa A and he’s given no thought to scaling back his all-round duties in the two-Test series which follows.

Watson was barely able to move in the dressing rooms after the back spasms stopped him mid-over on Sunday, and that injury followed a hip strain which ruled him out of the previous two tour matches.

But Watson said on Tuesday “continual management”, not resting, was his preferred approach to getting the best out of his body.

The 30-year-old broke down repeatedly early in his international career and has worked hard to be able to consistently star in all forms of the game.

“Playing a lot isn’t something that over the last couple of years I ever thought I was going to be able to do,” Watson told AAP on Tuesday.

“So in the end it’s just continual management to be able to try and stay on top of things.

“When I’m playing so much it means I am pushing my body all the time, so there’s a chance little things can pop up and unfortunately it’s been two things together over the last week or so.

“But they haven’t been major things. I’ve just got to continue to stay on top of my general management and hope we can get on top of these things pretty quickly.”

Team physio Alex Kountouris has been working hard with Watson to release the effects of the spasm from his back in time for Friday’s match.

“Definitely, it’s a huge match in the scheme of things, so no doubt I’m desperate to get back to be able to play,” said Watson.

He said the latest injuries had not made him consider asking captain Michael Clarke for a move down the Test batting order from opener, to ease some of his workload.

“No, not at all.”

“The plan is to hopefully be able to recover over the next couple of days and that means that it won’t really affect my Test preparation at all.

“It hasn’t been determined yet but in a perfect world I’ll play the tour match to be able to get my bowling workload up more than anything and also try and get some form in the longer version of the game.”
