Fiat Bravo starter broken?

Just another quick question to all, i removed the starter(cheers Ian for the advice) and took a look at it, in between the rotate bar and the outer rim some of it was broken, would the metal fragments have gone in to the gearbox or would it be o.k...?
i dont want to be p***ing in the wind and get a new starter and the the gearbox goes without having knowledge first
Any answers much appreciated
