Due to the absence of Cathal McShane, Peter Canavan believes Tyrone do not have a chance of winning an All-Ireland this year.
The full-forward was one of the county's star players last year as they reached the All-Ireland semi-final. He turned down the chance to join AFL side Adelaide Crows earlier this year but suffered an ankle injury during a National League game.
His rehabilitation suffered a setback earlier this month which has ruled him out for the season.
"Prior to Cathal's announcement, I would have given Tyrone a chance [of winning the All-Ireland] because we had good news in terms of Mattie Donnelly coming back from a very bad injury and he's playing well with his club at the minute," Canavan told Sky Sports' new GAA show 'Inside The Game'.
"But can we win an All-Ireland this year without this man, Cathal McShane? The answer is no, unfortunately. I don't think we have anyone who will step in there to complete the job he was doing.
"As a target man last year, he was something else. He ended up with an All-Star. Every time Tyrone had the ball and they were moving forward, they had a focal point. So many of his runs are focused around the D. If he does win possession, he's close to goal.
"Tyrone were playing a more heads-up type of football whenever Cathal McShane was there.

"So if you want to compare - would Kerry win an All-Ireland without David Clifford? I would say definitely not. So likewise that's why I'd say Tyrone would find it very hard without McShane.
"The facts speak for themselves. 3-49 he scored last year. He ended up getting his first All-Star.
"From a Tyrone point of view, there's a number of players that could have got injured that may not have been catastrophic. But, in my opinion, the one player we didn't need to be getting more setbacks was Cathal McShane."
