The junior played 14 minutes on Tuesday night as the Cardinals dusted Hofstra 97-69 before 20,112 fans at the KFC Yum Center to go 2-0 on the season.
"I think the 14 minutes were great for him," Pitino said. "I knew I was not going to play him a whole lot tonight, but I wanted to play him some."
Behanan, who was a member of the Final Four All-Tournament team last season and the West Regional MVP two years ago, was suspended for disciplinary reasons in mid-October. Pitino said it would be "tough" for him to make it back.
But last week, Pitino said he had made it through a tough period in good order when he wasn't allowed to do any basketball activities with the team and wasn't living in the dorm. He still isn't back in the dorm and wasn't allowed to speak with the media after the Hofstra game.
Behanan was back on the court and finished with four points, one rebound and one steal in 14 minutes for the Cardinals.
"He gives us an extra body in there and one who knows the system," Wayne Blackshear said. "It's great to have him back for us."
Added Stephan Van Treese: "I feel like we have a full team now, it's energizing for us. Chane is a bull on the boards."
Pitino said Behanan will get some more minutes on Friday night against Cornell and then "he will be fine."
"I am really proud of him," Pitino said. "What he had to do? Very few of you could do what he has done. It took a lot of discipline from a very undisciplined young man. For 30 straight days he had to do this and it was not easy.
"To get yourself up at 5:45 or 6 in the morning, and he still has a long way to go with this stuff, but he has done a remarkable job for 30 straight days of never going out, not one day. For 30 days, for Chane that's an impossibility. No visitations, nothing. That's a pretty good performance by him."
