South Africa's Morne Morkel won't change bowling style

South African bowler Morne Morkel insists he won’t change his bowling style, even though he holds the unwanted world record of having the most Test wickets chalked off for no-balls.

The paceman has had 13 wickets denied, more than anyone else in history, because of his front foot being over the popping crease.

Two of those wickets came at Lord's in the first Test defeat to England, but Morkel remains confident in his style.

Speaking ahead of the second Test at Trent Bridge, live on Sky Sports, Morkel said "It's not going to end my career.

"It's 13, yes - world record. Somebody needs to hold it. It's 13 wickets I'd like to have in the bank, but it wasn't meant to be.

"(England) also bowled a couple of no-balls that could have easily taken a wicket."

Dean Elgar, who captained South Africa at Lord's but will pass responsibility back to Faf du Plessis on Friday, described some of South Africa's mistakes as "non-negotiables" and Morkel holds his hands up to his errors.

"It's not acceptable. It's a controllable sort of thing," he said.

"I can't make excuses. I need a lot of rhythm, and timing for me is crucial, and I felt the more I bowled in that Test the better my timing was.

"Unfortunately, I did bowl that no-ball, and that's the sort of thing you don't want to give quality players extra lives. You're going to get punished.

"The only thing I can do is keep on working on getting that foot behind the line. I think it's just a rush of blood to the head, wanting to create something with the older ball."

Morkel's contribution will be more important than ever, in the absence of his fellow pace bowler Kagiso Rabada, who's serving a one-match ban for swearing last week.
