Question for any rugby players

[PoBoy321]

So I played rugby freshman year, took off last year (took off first semester to focus on grades, second semester because i broke my hand) and now I'm getting back into it. I was always a lock but now we kind of have a shortage so they have me in as a prop now. The problem is my neck is always killing me. Does anyone know any good excersises or stretches to try to prevent this?
