Wales captain Alun Wyn Jones will equal the world record for most international rugby union appearances in Saturday's Guinness Six Nations clash against Scotland, which is still scheduled to go ahead despite widespread cancellations in face of the coronavirus outbreak.
Jones' 148th Test, a tally that includes nine for the British and Irish Lions, matches the figure set by New Zealand's World Cup-winning captain Richie McCaw between 2001 and 2015.
Wales head coach Wayne Pivac, has made four changes to the team beaten by England last weekend, calling up uncapped Sale Sharks prop WillGriff John, fellow front-rower Wyn Jones, lock Cory Hill and scrum-half Rhys Webb.
Hill, who makes his first Wales start since February last year, replaces Jake Ball after he suffered a shoulder injury in the England game.
John takes over Dillon Lewis, Jones is in for Rob Evans and Webb is preferred to Tomos Williams.
Webb, who was unavailable for Wales during his time with French club Toulon because he did not meet the minimum 60-cap eligibility rule for players plying their trade outside Wales, has not started a Test since November 2017.
Meanwhile Scotland head coach Gregor Townsend has made three changes to his starting XV.
Hooker and vice-captain Stuart McInally, number eight Magnus Bradbury and second-rower Sam Skinner come into the side, with the latter starting for the first time in the campaign.
Fraser Brown and Scott Cummings drop to the bench, with Nick Haining unavailable through illness. Matt Fagerson joins the match-day squad to replace Bradbury.
Townsend has named the same back division for the third match in a row, with captain Stuart Hogg set to move into joint seventh place on Scotland's all-time appearance list, overtaking Greig Laidlaw and John Barclay to join Jason White and Nathan Hines on 77 caps.
Scotland head into the game in Cardiff on the back of an impressive 28-17 victory over France at Murrayfield which ended the visitors' hopes of the Grand Slam.
"We set out this season to improve our consistency over a run of five tough games, something we have done well so far," Townsend said.
"We've stayed in the fight in every game, which is a credit to how hard the players have worked in training and during the Tests.
"It's also been encouraging to see how well the players have grown together and have taken on board the input from new coaches, Steve (Tandy) and Pieter (De Villiers), who have done a great job in their first season with the team.
"We have huge respect for the Welsh team, who narrowly missed out on a World Cup final a few months ago. They are well coached and have some outstanding players.
"It will be a fantastic occasion and one last opportunity to play to our potential in this championship."
