Tyrone manager Mickey Harte has made a single change to his team for tomorrow's All-Ireland SFC quarter-final against Dublin at Croke Park (throw-in 4pm).
Harte has switched one McGuigan brother for another, as Brian replaces Tommy in the half-forwards.
Tommy McGuigan's exclusion is a forced change to the side which beat Monaghan in the Ulster decider, after he picked up a knee injury during the closing stages of the 1-14 to 0-7 win.
This means that Stephen O'Neill once again has to be content with a place on the bench, despite the Clan na nGael clubman's return to full fitness.
O'Neill has recovered from a heel injury, having taken part in the Red Hands' last three training sessions; and is likely to feature at some stage tomorrow afternoon.
The 29-year-old had missed Tyrone's entire National League programme due to an elbow injury sustained in the McKenna Cup final in January.
The Ulster success showed that Tyrone are live contenders for the All-Ireland title, but Harte has urged his charges to park that and be ready for a new challenge.
"We wouldn't expect to go into this game with any fear, but we would have to go in with a certain amount of caution," he told Q101 sport.
"The last encounter we had with them was in Omagh in our last league game and we needed to win to survive, and they had almost qualified for the league final and were only put out on score difference.
"Our latest encounter is one that they will be quiet happy with, and we realise that it is a different team perhaps than we have played in either 2005 or 2008; so we need to be ready for the new challenge and I believe that if we are, we should be good enough to do it."
