Netherlands international attacker De Jong continued his recovery from a long-term injury, as he started the Under-21 side’s game against their Aston Villa counterparts in the Under-21 Premier League at Villa Park.
The former Ajax star played for 72 minutes and provided an assist, and Beardsley was pleased with his contribution to the 2-1 win.
“Siem is a top player and I'm a fan of his,” Beardsley told Newcastle’s official website. “I was lucky enough to see him play for Ajax when they won the league on the last day of the season three years ago and he's a player, there's no doubt about it.
"He didn't want to come off tonight - he wanted to keep on going but I don't want him to get injured so that's why I took him off.
"The plan was 60 to 70 minutes and I kept asking how he was, but with it only being his second game back it was a nice bonus for us.”
De Jong has not played a single competitive game for the Newcastle first team for the past eight months due to fitness concerns.
The 26-year-old Dutchman first picked up a thigh injury in training in September, and then suffered a collapse lung.
However, it seems that De Jong is ready to return to competitive action and cannot stop playing football, which is good news for the Newcastle fans.
John Carver’s side will return to Premier League action against Swansea City at St. James’ Park on Saturday, and one suspects that the 2014 summer signing from Ajax will play some role in that encounter.
