Why on earth would you drop him after that performance? He is fit, he's proved it. He's not had a muscle injury and isn't in his mid-30s, "managing his game time" should not be a thing at this point, especially given we're not playing any cup games so he'll get a rest every few weeks anyway.
Because it's all about recovery.
It's got nothing to do with the type of injury.
He's come from nowhere and completed 95 minutes of high-intensity Premier League football. His first senior appearance in over 10 months.
Maybe managing his game time was a bad way of putting it, but managing his levels of fitness moving forward.
Training doesn't prepare you fully to go and then play two games in three days on the back of 10 months out.
