Kyle Sinckler has been called up to the British and Irish Lions squad for the upcoming tour of South Africa, following Andrew Porter's injury.

Tighthead prop Porter has been ruled out of the series due to a toe problem, which the Ireland international sustained on Friday while in action for Leinster.

Sinckler was a big-name omission from the original selection, but Warren Gatland has now called up the England prop.

Following his omission from the 37-man squad, Sinckler had said it "didn't make sense" to him that he had been left out. He has previously toured with the Lions in 2017, when the team visited New Zealand.

The Lions squad will convene on June 13, taking on Japan in Edinburgh 13 days later before heading out to South Africa, with the tour culminating in a three-Test series against the Springboks.

"It's really bad luck for Andrew and we send him our very best wishes for a quick and successful rehab," said Gatland.

"Andrew is a young man with a big future ahead of him and I'm sure he'll be in contention again in four years' time."

And the former Wales coach hopes Sinckler proves him wrong for his initial decision to leave him out.

"As always in rugby, when there's an injury there's an opportunity for someone else," Gatland added.

"I have been very pleased to see the way Kyle has responded to initially being left out of the touring party.

"He's showed some excellent form of late and I hope he continues to stick two fingers up to me about leaving him out in the first place."

The Lions last toured South Africa in 2009, when they lost the Test series 2-1.
