Six Nations:Centre Jonathan Davies is a fitness doubt for Wales' Six Nations clash against Italy in Rome on Saturday.
The Scarlets player is battling to overcome a hamstring injury suffered when Wales beat Scotland 24-6 at Murrayfield nine days ago.
If he is ruled out, then Wales coach Warren Gatland might have to consider switching the versatile James Hook from outhalf, although Stephen Jones and Rhys Priestland would also be midfield options.
Wales assistant coach Neil Jenkins said: "Jon is a doubt at the minute. He is doing rehab and stuff, and we will have another look at him tomorrow.
"Hopefully he can make it. He hasn't done a great deal with us since the Scotland game, other than rehab. We will wait and see what happens."
Gatland is due to name his match-day 22 tomorrow, and there could be a place for Cardiff Blues wing Leigh Halfpenny.
Halfpenny was ruled out of the England and Scotland games earlier this month because of injury, but he is close to making a comeback.
Jenkins added: "Leigh trained with us today, which is great news. Everything seems great with him - he's on the way back."
