Wales centre Jamie Roberts has admitted that he is struggling to make Friday's Autumn International clash with Samoa.
Roberts suffered concussion in last weekend's defeat to Argentina, but he has revealed that no lasting damage has occurred.
"I hope to play against Samoa, fingers crossed, but I have to go through the protocols. I did not suffer any memory loss and the medics have taken good care of me," Roberts told Sky Sports News.
Roberts has made 45 appearances for his country.
