Scarlets lock Jake Ball in doubt for Wales Tests against Tonga and Samoa

Wales lock Jake Ball has become a doubt for their Tests against Tonga and Samoa after suffering a shoulder injury whilst playing for Scarlets.

"It's just a fight against time. We'll know more in a week or two," Scarlets head coach Wayne Pivac said.

"But he's doing everything he can to play some more rugby this season.

"Hopefully should we make the final then he'll be reassessed."

As a result of the injury, Ball will miss Friday's PRO12 semi-final against Leinster in Dublin.
