England seamer Ollie Robinson feared he would have to bring his career to an early end due to injury,

The 29-year-old has played a big part in England's first Test series win in Pakistan, taking five wickets in Rawalpindi and three in Multan.

Robinson had suffered a series of injury setbacks and came in for criticism for his lack of fitness during the Ashes series hammering in Australia at the start of this year.

Back issues badly hampered Robinson and he was concerned that his playing days could be over.

"I kept coming back to full fitness, then getting an injury or illness, then another injury," he told BBC Sport.

"There were points when I didn't think I was going to play for England again, or play cricket again.

"I thought 'I might have to look at what else I can do here, I don't think I'm going to be able to carry on playing cricket'."

England will attempt to secure a whitewash of Pakistan in a third and final Test that starts at the National Stadium in Karachi on Saturday.

Robinson is savouring a special tour following such a challenging period.

"It's probably the toughest 12 months I've had as a professional cricketer," said Sussex's Robinson.

"It's a really proud tour for me, in the fact my body has got through it, I've bowled well and I've proved to the world I can do it in any conditions.

"It's been tough and there have been some dark days, but series wins like this make it all worthwhile."
