mystery injury

How does a pitcher , in this case Marino Revira get injured when he has no injury colume on his card? Also he is set to come in only after the 8th inning,but was braught in in the 7th. AI not paying attention or what?

Pitchers are injured when the opposing teams DH rolls 6-12.

For the second question I’ve got nothing. HAL does what HAL does LOL
