What happend at half time V Kerry??

I am not sure if anyone noticed when Kildare team came back onto the field after half time against Kerry. As we all know the 2 Cribbens were substituted. Paul was still walking out in his jersey with not training gear or tracksuit on and looked really annoyed. Keith was nowhere to be seen. Flats was pointing and talking to a few players and eventually went wing back in Pauls position but it all seems very hurried. Was there a bit of a row at half time? Paul was playing well and surely if he was injured would of came back out with gear on him to keep warm. He looked really P***ed off. Also the rush to get lads into position with flats eventually going wing back???. Maybe The Cribbens were both injured or it was tactical but found it really weird?
