Back squats, behind-the-neck work and heavy carries are what an irritated neck usually objects to. Front squats with a cross-grip, neutral-handle pulldowns and chest-supported rows are the usual substitutions people make.
The honest limitation: RepRoute's exercise catalogue carries usable joint-safety data for seven regions — shoulder, elbow, hip, lower back, knee, ankle and wrist. The neck isn't one of them. Exactly two exercises in the whole 899-movement catalogue carry a neck tag — Cross-Body Crunch and Crunches — so flagging your neck records the injury on your profile and, in practice, changes nothing about your plan.
Tagging the catalogue for the neck by guesswork would be worse than the gap it fills — a wrong safety tag is a wrong exercise put in front of an injured person. Until that data exists and has been checked properly, we say so plainly rather than counting two crunch variants as coverage.
The manual route works well here. Flag the neck so it's on file, then use Swap during your session on any movement that loads it — a bar on your back, a heavy carry. Swap hands you another exercise in the same pattern that fits your equipment, one tap at a time.
