Ireland coach Declan Kidney says he will continue to assess the "different combinations in my head" as he prepares for next month's World Cup.
Kidney watched his side lose narrowly 10-6 to Scotland at Murrayfield.
"I am giving players a chance to play their way into the squad and no-one let themselves down at Murrayfield - when the tough selection decisions have to be made we'll make them," said Kidney.
"We didn't deserve to win this game so fair due to Scotland," he added.
"They attacked us and kicked a few balls to touch when they could have taken three points.
"We were in it with a few minutes to go but it's always disappointing when you lose to a late score.
"We didn't have any more ring rust than Scotland so I've no excuses as to why we lost.
"There were some positives, such as new caps Felix Jones and Mike McCarthy, who both made very good contributions.
"We have a few bangs and knocks which will take a while to recover but we'll get the fellas up and going again for next weekend.
"We want to get as many players playing as possible, whether that's in Bordeaux against France or with their provinces.
"Overall I'm pretty pleased - we had some young players out there and you will only gain experience by playing matches.
"We have a match under our belt now and in future we'll gain from that."
