Martin O'Neill has given a fresh injury update on Celtic's squad as they prepare for their Premiership opener against Dundee on August 3. The Hoops boss revealed midfielder Benjamin Nygren is currently sidelined with an Achilles problem, while Auston Trusty is set to return to training after being granted extra time off for family reasons.

What's the latest on Celtic's injured players?

O'Neill confirmed Nygren didn't feature in Celtic's friendly draw with AC Milan due to his Achilles issue, though the manager doesn't believe it's a serious concern. The Swedish midfielder played for his country at the World Cup, which may have contributed to the problem. Trusty, another World Cup participant, will rejoin the squad on Monday after being given additional time off.

How is Celtic's pre-season shaping up?

The Hoops have been carefully managing their players' return from international duty. Those who went deep in the World Cup haven't featured in pre-season friendlies, while others like Kieran Tierney and Anthony Ralston have been eased back in. Yang Hyun-jun has returned to full training after a minor setback, and Alistair Johnston was close to featuring against Milan.

What does this mean for Celtic's league opener?

Celtic will begin their title defence on Monday, August 3 against Dundee. They finished last season in strong form, winning their final five games to secure third place with 67 points from 33 matches. The Hoops are currently three points behind league leaders Heart of Midlothian, who they'll face at home on October 17. With key players returning to fitness, O'Neill will be hoping for a strong start to the campaign.
