Yes, he missed 1 game. It's unlikely Yeboah's knee is anywhere near as damaged as Eugene's.
His knee hasn't taken nearly the damage Omoruyi's has, but I can't discount it, either.
Earlier this year, I went and read some of the Stony Brook board's game threads. Yeboah sprained his knee at the start of the Quinnipiac game on 12/22, missed the Northern Iowa game on 12/29, and was back with a structural knee brace from 1/5 until 2/2. There were a lot of comments from fans that he was "not playing 100%" or "isn't nearly as quick since the injury" and that the brace was limiting his mobility.
Up to the game with the injury, he'd been averaging 20.0 ppg on 39.8% shooting from the arc.... after he came back, he averaged 15.2 ppg on 26.6% shooting from the arc. He also went to the line a lot less after the injury, dropping from 5.6 attempts per game to 3.2.... which may have meant he was going less aggressively to the rim. His assist numbers also doubled once he came back, which may have meant he was looking more for open players rather than looking to score.
Was hoping it was just a temporary blip and he'd come into this season fully healthy - but now he's out 1-2 weeks with another minor knee injury. I don't know if it is the same knee, or the same problem, or any details - but there's enough there for me to be concerned about his stability this year.
