Ben Stokes has revealed he should be fit to bowl during England's tour of South Africa after scans confirmed he had not sustained a knee injury.

Stokes complained of a knee problem during the first day of England's second and final Test against New Zealand in Hamilton,.

However, he did bowl 25 overs during the Test, which was drawn as England lost the series 1-0.

The all-rounder - a star of England's Cricket World Cup and Ashes campaigns - has now confirmed he will be fit to bowl against the Proteas, with England's four-Test tour to begin on Boxing Day.

"It's alright," Stokes told talkSPORT. "I got some scans when we got back [to] England and there's nothing really showing up on the MRI scans, which is good news.

"I just need to toughen up I guess but it's alright and it's just treatment now. I will be fine to bowl [in South Africa]."

After a difficult Ashes series and a poor performance with the bat in the first Test in New Zealand, Joe Root returned to form in style in Hamilton, scoring 226 in the first innings, and Stokes claimed he backed the England captain to hit a double century ahead of the tour.

"Rooty is one of the best players in the world. He obviously went through a little bit of a dip in performance but that is natural, he’s human. The old saying is form is temporary and class is permanent," Stokes added.

"It's obviously great for English cricket to see Joe go out in his last innings before a big tour and hopefully we can see Rooty scoring runs like he normally does.

"Being Test captain is one of the toughest jobs and one of the most criticised and how people speak about you is dependent on how well the performances on the pitch individually and as a team.

"It's unfair most of the time that when things don’t go well the captain gets it all. I actually called Joe to get a double hundred on day one of our first warm-up game to Rory Burns. I think I was stood at slip and I said, 'Joe is going to get a double hundred this tour'."
