The Rovers captain was forced off during Saturday's match at Nottingham Forest with a suspected broken arm after an altercation with Forest striker Darius Henderson.
The defender left the City Ground with his arm in a sling and subsequently went for an x-ray.
The results of the scan showed there was no damage and Dann is expected to take his place in the heart of the Rovers defence this weekend.
