I came across a glitch where a player recovers from injury (Godfrey in the screenshot) but his injury icon lingers. He is no longer on the injury report so I feel like it's safe to assume he's healthy. As you can see, he no longer has OUT/QUESTIONABLE/PROBABLE next to his injury, it's just blank. I currently see this for four of my players who have been injured and recovered, so this is not a one-off glitch.
