Dublin manager Jim Gavin has eased injury fears surrounding Cian O'Sullivan by confirming the experienced defender will be fit for the All-Ireland final.
O'Sullivan is one of just three players, along with Stephen Cluxton and James McCarthy, to have started all five of Dublin's final wins this decade.
But he was replaced with an apparent hamstring injury in the first-half of last weekend's semi-final win over Galway, prompting fears he could miss the 2 September clash with Tyrone.
O'Sullivan has a history of hamstring issues and revealed after the 2015 win over Kerry that he overcame a 'bad tear' to play having been told at the time to 'plan for the worst'.
Gavin said that O'Sullivan had merely experienced a 'tightness of the leg' this time and didn't train with the team on Wednesday evening but could return to action over this weekend.
"It was just a tightness that he felt, that was all," said Gavin. "We weren't going to push it in a competitive game like that so we just took him off and it worked out for us.
"It's good news. You get the normal bumps and bruises that you would associate with a Championship game, but we are healthy, which is great."
Gavin described O'Sullivan as a key part of Dublin's defence as they prepare for the challenge of the Red Hands.
"He is a leader for the team, he drives standards, both on and off the pitch," said Gavin. "He is obviously a very experienced player and I have been fortunate to work with him through a lot of it. There are a group of players with that experience and it is important going into games like this that we can trade off that."
Gavin and Tyrone manager Mickey Harte were locked on three All-Ireland wins apiece until Gavin overtook the 2003, 2005 and 2008 winning boss with four in 2017.
"He's one of the great managers," said Gavin. "Obviously he saw the current crop of players coming good as well and how talented they were.
"But I think it's just a testament to his passion for Gaelic games. It comes to the fore when you hear him speak about the game. He's had great success in the past and he will have great success in the future."
Gavin faces a selection headache regarding Bernard Brogan who returned from cruciate knee ligament surgery to appear as a sub against Roscommon in the Super 8s but didn't feature last weekend.
"They all want game time, but they understand that in team sport it's about the team, it's about the collective," said Gavin.
