The 29-year-old centre-half is not right despite playing the full 90 minutes as captain in Wednesday's 2-1 Carabao Cup defeat at Villa.
It is another defensive problem, with Willy Boly out for several months after having surgery on a fractured fibula.
"He is not OK. He had this problem last week. He played at Villa, knowing he still had his problem," said Nuno on Bennett.
"Let's see how he recovers, and, hopefully, he will join us soon, but he is not OK for tomorrow."
Wolves are also assessing the fitness of Morgan Gibbs-White who has missed the past couple of matches with a back injury.
"He is dealing with lower back pain. Let's see how he recovers from that.
"He has trained today outside with (rehabilitation coach) Joao Lapa.
"He's not totally pain-free, but let's see how he is. He's dealing with that pain."
