Bennett has returned to the team after battling a back injury since September.
He made his first Premier League start of the season in the Cardiff stalemate to earn praise from the manager.
Lambert said: "I thought he did great. That was his first 60 odd minutes in months. I thought he did ever so well considering he hasn't done much at all, he came in and I thought coped very well.
"He had the problem with his knee and then his back, but that's his first real test in earnest in four months or so.
"I don't think there's any issue with his confidence, it was only match fitness why we took him off."
