Ben Stokes has revealed that he is back to full fitness as England gear up for their first Test against South Africa.

The 24-year-old all-rounder suffered a dislocated shoulder during the third Test with Pakistan last month but has recovered in time for the tour and struck an unbeaten 158 in a warm-up match in Potchefstroom today.

"I've got back to fitness quicker than I thought I was going to. I had two or three weeks back home in the indoor nets with Durham and then had a couple of good training sessions," Stokes told Sky Sports News.

"It's always nice to get runs in these warm-up games but now it's just a case of not getting too far ahead of myself and trying to keep the same form that I've shown here and take it into the first Test.

"I'm fully fit to bowl; I've done the same amount of bowling work back home as I have done batting."

The first Test with South Africa gets underway in Durban on Boxing Day.
