Celtic midfielder David Turnbull is definitely out of the trip to St. Mirren this evening through injury, Football Scotland report.

The Lowdown: Turnbull under Postecoglou

Turnbull has been an ever-present figure under Ange Postecoglou this season, featuring in every single game this season.

He’s scored nine times and registered seven assists in all competitions but hobbled off at Hampden Park on Sunday as the Hoops won the Scottish League Cup.

Postecoglou recently praised the Scot and admitted that the 22-year-old has been given ‘information’ every week in regards to improving his game. However, it now seems as if he is the latest man to join Celtic’s long injury list, just as they showed signs of slowing up with Kyogo Furuhashi returning against Hibernian on Sunday.

The Latest: Postecoglou’s comments

Football Scotland shared comments from Postecoglou in a story on Wednesday morning.

The Hoops boss confirmed that on-loan winger Jota looks set to remain sidelined until after the winter break, before having this to say on Turnbull's hamstring issue.

“Dave was the major one coming out of the Final. We have had the scan, but we haven’t had the results yet.

“He will definitely be out for St Mirren, but I’m not sure how long he will miss.

“Everyone else got through the game okay, but there are one or two minor niggles.”

The Verdict: Get to the winter break…

Celtic could do with the winter break coming as soon as possible, in all honesty. Postecoglou has had to deal with multiple injury problems all season at Parkhead, with Turnbull’s the latest. He's been relied on heavily by Postecoglou and even filled in at centre-forward recently, with the likes of Furuhashi, Albian Ajeti and Giorgos Giakoumakis all out.

Celtic have actually made a request to the SPFL to bring forward the winter break to coincide with the three-week restriction on supporters attending games, and that would also give Postecoglou’s squad a much-needed breather and the chance to get some players back.

The Hoops have to face St. Mirren, St. Johnstone, Hibernian and Rangers before the scheduled winter break, and it seems as if they may have to do that without Turnbull, should the scan confirm the worst.
