No, he did hurt it. He had surgery around the 2nd week of Dec, which would mean 5-6 weeks post surgery now. I have heard no updates, but given what I saw from my son's knee surgeries, it wouldn't surprise me if his rehab is going well that Fran would mention his knee being structurally fine now and just trying to strengthen and get range of motion back.
That doesn't mean he would be able to try to play this year, it takes a long time to catch it back up to where it was before the injury, just that there would be hope he could be back next year. Also keep in mind, even if he were to play in the PTL, it's likely he may not be back to full speed/strength even one year post surgery. We would likely notice a bit limited speed, jumping, explosiveness next season from him. If he's given a 6th year, that year would probably be as close as possible to what he could be.
