There's not much of a training/playing load-injury relationship for ACL tears. It's likely that just playing more games overall might increase the overall risk, as you just have more opportunities to do so, but you're also getting the conditioning benefits from that (as long as you're able to do it without picking up other injuries) that offset that increased risk somewhat as well.

There's plenty of other injuries that are the near direct result of overtraining/overplaying. Bony stress injuries/stress fractures in younger players and tendon injuries (primarily tendinopathies, rather than tears) are the big ones, and are a major concern. ACL just isn't really on that list.
