Hardware damage – The lens does not lock on the Nikon D7000

A strap is broken on my bag. My Nikon D7000 had a heavy 70-200 2.8 attached. When I took it out, the lens was detached from the body and did not twist to lock itself. I tried the other goal that I had with the same result. I tried the lens on my other body, and that was fine. Can this body be repaired?
