 Jones has been plagued by knee injuries |
Swansea and Wales squad midfielder Owain Tudur Jones has been ruled out of action for four to six weeks. Jones has been plagued by a knee problem since the end of last year and only returned to the side last month after surgery in the close season.
"We'll treat Owain conservatively, the area operated on is still maturing," said Swansea physio Richie Evans.
Swans midfielder Darren Way remains out for an indefinite period and Darren Pratley is out of the Port Vale game.
Skipper Pratley could also be struggling for the following weekend's fixture with Bristol City, meaning manager Kenny Jackett could look for a midfielder on the loan market.
