STEPHEN WELSH has suffered a nasty head knock during Celtic's Sydney Super Cup opener.

The youngster clashed heads with Sydney star Jake Girdwood-Reich in the 75th minute and as a result he had to be treated for a nasty gash on his head.

Welsh was then substituted as Bosun Lawal came on to replace him for the closing stages in Australia.

It remains to be seen if the head injury will rule him out of this weekend's fixture against Everton.

The Scotland youth international started the fixture as Ange Postecoglou's side were defeated against their Aussie opponents.

Kyogo Furuhashi opened the scoring before Robert Mak and Max Burgess turned the game on its head.

Meanwhile, Celtic captain Callum McGregor is stepping up his bid to return from injury during the club’s tour to Australia.

The midfielder has been sidelined since sustaining a knee injury in the Champions League match away to RB Leipzig at the start of October.

However, he was pictured running with his team-mates on Wednesday after they arrived in Australia to prepare for the Sydney Cup.

“Hopefully I will be joining bits of the sessions this week and just progressing the rehab,” McGregor told Celtic TV prior to the first training session.

“It will be an important five, six days for me. I am looking forward to getting back on the grass with the boys.”

McGregor is adamant the trip Down Under to compete in the Sydney Cup is valuable for Celtic in terms of maintaining sharpness, while also giving their fanbase in Australia a rare chance to watch them in action.

The Hoops faced Sydney FC on Thursday and then Everton on Sunday.

“It’s still a really important period for the team,” said McGregor, whose side will face Aberdeen away on December 17 when they return to cinch Premiership action after the World Cup break.

“It’s important to come and see the fans over in Australia. We have that responsibility to come and see the supporters. We’ve bumped into a few of them.

“These guys get up in the middle of the night to watch the games and it’s important the club acknowledge that.

“We’re here to do that, but at the same time we’re here to work and continue the fitness. We’ve got a four-week break before the league starts up again, but it’s important to maintain the standards in the way we want to train and play.”
