Player vanished halfway through game

My star wide receiver (Nyck Harbor) just up and vanished early in the third quarter through the end of the game. I (South Carolina) was playing Alabama, undefeated going into the game, and I was keeping pace (barely) with 'Bama through the first half and part-way through the third. Then I couldn't keep up. I checked my personnel on the field and noticed Harbor wasn't on the field where he should be. Maybe I missed an injury or something, I thought. Checked my injury report and no players were injured. Checked my depth chart and Harbor was still there. But he never appeared on the field again the rest of the game. Got blown out. Having the fastest player on the field (seriously, Harbor is like having a cheat code - not realistic (yet, he's young)) just not play makes no sense at all. I even moved him over to WR1 and he still never showed up on the field.

Anyone else see this kind of thing?
