Wales second-row Jake Ball will return for the Scarlets in the Pro14 Champions Cup play-off against Ospreys.

Ball has not played since Wales' Grand Slam triumph against Ireland on 16 March with a foot injury.

Hooker Ryan Elias returns, but Scarlets face a potential prop problem with Wales duo Samson Lee (HIA) and Wyn Jones (knee) battling to be fit.

Prop Rob Evans is a long-term injury so Scarlets could be short in the loose-head position if Jones is unfit.

Wales flankers James Davies and Aaron Shingler will again be missing, along with centre Kieron Fonotia who has a knee problem.

Shingler has not played for almost a year after suffering a knee injury in the Pro14 final defeat to Leinster and his recovery has been put back by a back injury.

Scarlets coach Wayne Pivac says Shingler should be fit to start training with Wales after being named in the 42-man World Cup training squad.
