Scottish lock Nathan Hines is in line to be called up for the second test against South Africa after Lions scrum coach Graham Rowntree confirmed there will be wholesale changes in the forwards.

Wales' Alun Wyn Jones looks likely to make way in the second row with Hines, Simon Shaw and Donncha O'Callaghan the possible replacements.

And Rowntree promised a more powerful pack for the second test in Pretoria after being dominated by the Boks forwards.

He said: "When the lads watch that again they will be a bit embarrassed about what we didn't do.

"That just can't happen in test rugby. There could potentially be changes in all three rows of the scrum.

"There were eight scrum occasions in that first half, three of which we were penalised. That put us nine points down. We will be looking very hard at those scrums where we looked so vulnerable.

"The changes we made sorted it out. I was delighted with the impact Matthew Rees and Adam Jones had in that set-piece. The changes made the scrum better and we got some good playable possession."
