In brief: Depends

If the brain injury included a basal skull fracture, something called a carotid cavernous sinus fistula can form which commonly gets mistaken for a simple red eye.
Another possibility is that the blink reflex has been somehow blunted from the brain injury, and the eye is red due to dryness and exposure.

In brief: It can

This can happen if the eyes are open or don't blink well.
There are parts of the brain that control blinking and eye closure. The eyes can get dried out, bloodshot, and irritated.
