I do find the injury status page confusing, perhaps someone else can explain it better or correct me if I get it wrong.

The day to day column at the far left indicates not future injuries, but a record of how many days in the current PB season the player has been out with a day to day injury.

I would suggest you read the manual section on injuries...

EXCEPT
The manual is totally obtuse in its explanation. I suspect George Bush wrote this section when he was running the Texas Rangers into the ground.

The manual says:
"SPECIAL NOTE: A player who has used all of his occurrences can still get hurt. If you have a player who was injured during the corresponding MLB season, he will never be completely safe unless he has reached his total games injured total. If he does get hurt, he will be susceptible to a Day to Day injury, regardless of whether or not he was overused. Players will never, however exceed there real life injury totals.
Day to Day injuries due to overuse (Day to Day injuries) DO NOT count toward a players injury day total.
All other injuries do (Day to Day injuries to players who were injured in MLB but whose injury number has been reduced to "0"). "

I defy anyone to understand that!

Bottom line though, ignore the day to day injury column.
