The Swans captain has been out of action with a back injury, and gained more time with the Under-21s after coming on to score the winner during their League Cup win over CrawleySwansea City captain Garry Monk is nearer to returning to the first team after playing for the club's Under-21 side in their 3-1 defeat to Charlton Athletic.
The centre-back was able to come through 90 minutes during the U21 Pro Development League Two clash, and is getting closer to being fully match fit.
The defender, who is recovering from a back injury, has recently revealed he may be forced to leave the Liberty Stadium and seek a move elsewhere if he cannot force his way into Michael Laudrup's first-team plans.
The 33-year-old has made over 200 appearances since signing for the club in 2004, and captained the Swans as they won promotion to the Premier League in 2011, however the Danish manager has admitted it will be hard to fit the player into his starting XI.
The experienced defender recently scored the late winner to spare the team's blushes in their 3-2 victory over Crawley Town in the League Cup, and has insisted he will continue to fight for his place in the team despite being low in the pecking order.
