Injury on a home run

[greymule]

Yes, a home run creates awarded bases. The umps should have let a substitute runner complete the home run. (I guess the batter would be credited with the home run, but the sub would be credited with the run scored.)

Of course, a preceding runner could also reverse direction, grab the injured runner, and drag her around the bases, being careful not to create a passed-runner situation or aggravate the injury. Supposedly something like this happened in professional baseball long ago, in a play involving a fatal heart attack.

Now if the preceding runner had scored, could she still legally return to drag the injured player around the bases?
