Mowbray said: "It is great news. It is very clear what happened when you see the re-runs of the incident. We were fortunate enough to have three or four different camera angles of what went wrong. There is no contact by Paul or very minimal contact. That's why the club decided it had a very good case to appeal. In my opinion it was rightly upheld and I'm delighted. It's great news that we've got him available for the derby game. We didn't want to miss a player of his ability for two matches if we could help it. "
Robinson's other red card this year came against Birmingham when Damien Johnson ended up with a fractured jaw.
Mowbray said: "Paul's other sending off this year had a bit of controversy around it but I work with him every day and there is no malice in him. He is just trying to do his job and get on with his job. He is an excellent professional."
