Magpies football manager Geoff Walsh described the injury as significant and estimated Kelly could miss 10 weeks.
“Will Kelly had a serious hamstring injury … it’s a significant rupture to his hamstring tendon,” Walsh told the club’s website.
Defender Tom Langdon avoided surgery but remains at least three weeks away from a return while Jamie Elliott is progressing well from a hamstring injury with the club hoping he will be available soon after the bye.
Meanwhile Emirates Airlines has renewed its partnership with Collingwood for an additional five years, marking a quarter century commitment to the commercial relationship.
“The partnership between Emirates Airlines and Collingwood is one of the most significant and lasting in Australian sport,” Collingwood president Eddie McGuire said in a statement.
“At Collingwood we believe in offering a helping hand to those in need, which is why we will never forget the role our friends at Emirates played in helping Collingwood back on to its feet two decades ago.”
The deal began in 1999, the year Emirates launched services in Australia. It was the first major sponsorship struck by McGuire after he was elected president of the then struggling club in October, 1998.
The airline’s logo has featured on the black and white uniform across every season since the start of the partnership, including grand final appearances or premierships in 2002, 2003, 2010, 2011 and 2018. The Dubai-based company also gets access to Collingwood’s digital and billboard assets as well as rights to certain events.
“It’s a true partnership in every sense of the word and has created opportunities to connect travellers with an iconic Australian club,” Emirates divisional vice president Australasia Barry Brown said.
Collingwood are part of the airline’s sponsorship portfolio including Arsenal Football Club, Formula One and the Dubai World Cup.
The announcement comes 12 months after Emirates tightened its Australian sports portfolio by dumping its final horse race partnership, the company’s $2 million stake at Flemington races. This followed the end of its decades-long association with Melbourne’s spring racing carnival in February 2018.
