My starting center (Anna Maria, Knight) injured his ankle early in the second half of my most recent game. He wasn't able to return to play.

Despite this, I received no message from my trainer/assistant coach/whoever regarding the injury. In the past, I have always received a message regarding player injuries. I checked his health and it said 100. Anyone ever experience something like this before?

Yup

Yes. Exact same thing happened to my backup PG in my first game v. Monmouth this season (Ripon, Wooden). Starting PG played 40 minutes against an uptempo FB/FCP!

He hurt his pride and feelgoods.          

Happens all the time

That's common -- I just interpret it to mean the kid was held out the rest of the game as a precaution or something and thank my lucky stars he's at 100 percent and ready to go the next night. The wording in the PBP does make it confusing and invites one to fear the worst though.

Given that I have always received messages when I have had players get injured and return to the game a couple of minutes later, I was surprised not to receive one when a player couldn't return to action. Guess it's a common thing, thanks for the responses!
