'Injured' Player

[Rookie]

I had this situation a couple of games ago, and I am wonder if I did the right thing. The shoelace question made me think of it.

Situation: Team A gets rebound and goes down court on a fast break, I hear B1 scream for a time out, I don't grant this because they are not in possesion. But she informs me that B2 is hurt. I see that B2 is holding her face (no blood, no tears, etc.) I assumed she caught an elbow or a shoulder away from the play. She did not seem seriously hurt, so I let the game play on, and once team B had possesion I stopped the game and had the coach replace the injured player.
