New player joins the league...

... But a tier below the rest. We recently got promoted to pro since most players plateau'd mid season in rookie. Now we have a new player in the league but he can't race with us since he got placed in rookie when joining. Is there any way to get him up to us in pro? 

I have flagged to support. 

Hi Hampus, I have moved him to the Pro tier. :)
