After mechanic press in a new wheel bearing, I cannot Fit the caliper bracket over the rotor?

I recently took off the knuckle on my car and had my mechanic press in a new wheel bearing. When I went to put everything back together, I couldn’t fit the caliper bracket over the rotor. I even removed the bracket from the piston, and it still won’t fit over. The strut bolts, axel nut, tire rod castle nut and lower control arm bolts are all torqued properly. Not sure what the issue is. Is the hub not pressed in all the way? Because I don’t have nearly enough clearance.
