James Davies watches the Scarlets v Benetton action with brother Jonathan as he leaves the field with a medic

Guinness Pro14: Connacht v Scarlets Venue: Sportsground, Galway Date: Sat, 22 Sept Kick-off: 17:15 BST Coverage: Live score updates on the BBC Sport website

Wales flanker James Davies will see a specialist to discover the extent of the knee injury suffered in Scarlets' victory over Benetton last weekend.

Scarlets hope fly-half Rhys Patchell will be fit as he continues to undergo concussion protocols.

Davies will definitely miss Saturday's Pro14 trip to Connacht, as will his brother Jonathan.

Wales centre Jonathan has a hamstring problem, but hopes to return against Southern Kings on 29 September.

Prop Rob Evans and back-row Josh Macleod are still out, but number eight Uzair Cassiem (leg) is fit again.

James Davies suffered the injury in their 38-29 win over Benetton last weekend.

Head coach Wayne Pivac said: "We are not sure in terms of how long he will be out for and we will know more once he has seen the specialist.

"He is definitely out for this weekend and we will know more shortly."

Wales prop Evans is recovering from a shoulder injury and Pivac says he and Macleod should return in "around a couple of weeks".

Pivac added: "Uzair Cassiem is training fully with us and is available for selection this weekend."

Patchell missed the wins against Benetton and Leinster after suffering a head knock against Ulster in the opening Pro14 round.

Pivac said Patchell trained on Monday and they hoped he would do so again on Tuesday.

"If he comes through that he will be available for selection," added Pivac.

Scarlets back Clayton Blommetjies has not played since featuring at full-back in the opening weekend defeat against Ulster.

Pivac says the South African summer signing from the Cheetahs needs to work on his fitness.

"There is an adjustment period for Clayton and we are asking him to work on his conditioning," said Pivac.

"He has been asked to do a bit of extra work just to sharpen up on his match fitness.

"We do things a bit differently from the Cheetahs and expectation on the players is to be in a certain shape and Clayton has a bit of work to do in that area.

"He is doing that and is not far off making his return."

Wales wing Steff Evans will have another run-out for the region's A team in the Celtic Cup.
