2000 Ford Mustang Shifter

I have never had an issue with my clutch. It has been strong for 10 years. There have been times when I would be driving in reverse and than would not be able to shift it out of reverse easily and would have to drive back a little further in reverse and it would disengage and work fine. However, the other night the same issue happened and when it shifted out it seemed to go out off the gear track. The car is stuck in reverse. The clutch still works fine but only in reverse. I am wondering if this issue could be as easy as needing to replace the shifter? Any ideas.
