Alun Wyn Jones could make a sensational return to the British and Irish Lions squad after seeing dramatic progress in his recovery from the dislocated shoulder that appeared to have ended his tour.

Jones sustained the injury six minutes into the opening match against Japan on 26 June but is now training with Wales and Warren Gatland will make a decision on Tuesday whether to summon him to South Africa.

"A few weeks ago we didn't think there was an option and he's been back fully training with Wales. He's trained this week with them," Gatland said.

"I think he's doing a double session tomorrow (Tuesday) with them and we'll have to see what the outcome of that is.

"He's made a remarkable recovery from that injury which isn't as bad they first thought.

"That's a real positive and it would be a boost to the squad having someone of his experience and calibre to come in."

Munster's Conor Murray took over the captaincy from Jones but the Welshman's possible return would raise questions around the role.

Murray is set to make his first start since being named Jones' replacement in Wednesday's clash with South Africa 'A’, with Ireland team-mates Bundee Aki and Iain Henderson also in the side.

Murray has two previous Lions tours behind him and is favourite to form a half-back partnership with Dan Biggar for the Test series.
