Noel Whelan has admitted he is devastated Ryan Jack has been ruled out for Rangers ahead of Sunday’s game against Celtic.

The former Aberdeen striker, speaking exclusively to Football Insider, suggested the midfielder’s “worst nightmare” had come true with the news.

As confirmed on Friday, the 29-year-old has been ruled out of the rest of the season as well as Scotland’s European Championship campaign.

The midfielder has been missing since February with a calf injury that has plagued him all season.

He has played 24 times across all competitions this season.

Whelan suggested Jack would be devastated to miss out on this weekend’s Old Firm clash against Celtic, as well as Scotland’s Euro campaign.

“It’s come so close to the end of the season,” Whelan told Football Insider’s Russell Edge.

“The worst nightmare for a player is a bad injury that keeps you out of games like this one at the weekend and the Euros. It’s taken them so long to qualify.

“He’s had such an exceptional season, being part of Rangers side that has gone on to win the Scottish Premiership.

“He’s gained high accolades for his performances. I’m sure it’s absolutely gutting for Steven Gerrard but also for the Scotland camp.

“When they’re trying to put the best squad together to compete in the Euros, you miss a player like Ryan Jack who is a game-changer in himself.

“I’m devastated for the young man because these sort of competitions deserve the best players in the squads. He certainly is one of the better players in Scotland outfit.”
