Paul Dummett has suffered a setback on his return from injury – and is facing another spell on the sidelines.
The defender suffered a hamstring injury in May as Newcastle United fought the threat of relegation.
Dummett, keen to impress new head coach Steve McClaren, returned to fitness last month, and he was on the bench for the club’s Capital One Cup tie against Northampton Town.
But the 23-year-old was not among the substitutes against Arsenal last weekend, and he was not named in the Wales squad for the Euro 2016 qualifiers against Cyprus and Israel either.
Dummett – who was reportedly a transfer deadline day target for former Newcastle manager Alan Pardew at Crystal Palace – is understood to have suffered a fitness setback.
The problem is being assessed by the club’s medical staff, and McClaren could be without the player – who can operate at left-back or in the centre of defence – for several more weeks.
Dummett broke in the first-team squad at St James’s Park during Pardew’s time in charge of the club after successful loan spells at St Mirren and Gateshead.
The Academy graduate was handed a new long-term deal in late 2013, and Dummett is in line to new an improved contract once he returns to fitness.
Dummett – who can play at left-back and in central defence – was handed the No 3 shirt previously worn by Davide Santon, now at Inter Milan, in the summer.
Meanwhile, Wales beat Cyprus 1-0 in Nicosia on Thursday night to edge closer to Euro 2016 qualification.
And Newcastle-born Dummett is focused on helping his club and country this season.
