Osvaldo has been fined and transfer-listed after a training ground bust-up with Jose Fonte.
"Obviously what has happened has happened," Davis said after their FA Cup win over Yeovil Town. “As a team, as a squad, as a club, we are looking forward and we are very much together.
"We showed that again today and it is something we just want to move on from. It is something we want to move on and concentrate on what happens out there.
"Our dressing room is as solid as it has ever been and it will continue to be so."
Asked whether he can foresee Osvaldo being welcomed back into the fold after the altercation, Davis said: "Umm, well, we are a friendly bunch. We come and talk to you guys (the media) whenever you ask us.
"We've said for a long time that we have always had a good team spirit and a good changing room.
"That can't change and if anyone doesn't want to be involved in that then they are not welcome."
