Derry manager Brian McIver was pleased with the impact some of the new players in his panel made in the narrow defeat to Tyrone in the Dr McKenna Cup on Sunday at Healy Park.
The Oak Leafers went down to a 1-14 to 0-15 loss to Mickey Harte’s men in their first outing under McIver.
Ryan Ferris, Eoin McNicholl and Ryan Bell were some of the debutants for Derry in a new-look group.
McIver told RTÉ Sport: "I was disappointed with the result. I thought we deserved something out of that game.
"Many of them were starting county football where we gave five debuts and introduced young Declan Brown from the minors last year so that was six lads, and they all performed very well.
"A lad can look good in club football but you only really know how they can perform at that level when you see them in a county game. I was pleased with that.
"But I’m not happy with the result obviously."
Derry will host UUJ next Sunday in Celtic Park.
