Derry manager Brian McIver has made one change in personnel to the team for tomorrow's All-Ireland SFC second round qualifier against Down at Celtic Park.
The only change from last weekend's home win over Sligo comes in attack, with Eoin Bradley coming into the side at the expense of Ciaran McFaul.
Bradley featured as a 52nd minute substitute and scored a point in the seven-point victory over Sligo.
The Oak Leafers' former captain Gerard O'Kane might not have any role in Saturday's match, with McIver revealing: "A recurring knee injury originally picked up in a club game has made Gerard O'Kane very doubtful for the game.
"Ryan Scott and Benny Heron are both back in training but it will be a very late call to assess their availability."
The sides will be meeting for the second time in this year's Championship, with Down overcoming Derry by 2-17 to 1-15 in their Ulster SFC tie at the same venue last month.
Derry show five changes to the side that started that afternoon, with O'Kane, Scott, Brian McCallion, Aidan McAlynn and Cóilín Devlin all absent.
Into the starting line-up come Declan Brown, Dermot McBride, Sean Leo McGoldrick, PJ McCloskey and Conor McAtamney.
"Obviously, from a defensive point of view, neither team would have been happy about conceding 2-17 and 1-15. I would imagine you will see a totally different type of game on Saturday," added McIver.
"One of the ways you would like to work through the back door is to gradually build up momentum. That is obviously not going to be the case now.
"We will have to be at full throttle for this weekend. We know that is the case. It's a massive game."
