What if a runner is injured by a defensive player between bases & can't continue?

Definitely what MTR and Tony said. It's one of those "you'll know it when you see it" things.

Add one thing based on the title of the thread. This has nothing to do with whom may, or may not, be responsible for the injury. Could be an injury to a defensive player "caused" by an offensive player. Friendly fire also applies.
