The team's top defender started in the Hornets' 109-91 loss to the Blazers and played a surprising 34 minutes, finishing with 13 points on 5-of-8 shooting and seven rebounds.
"Being on the floor for the first time was really fun, but it's not about me; it's about the team and finding some wins," he said. "I'm happy to be back to say the least."
The 6-foot-7 Kidd-Gilchrist had surgery for a torn labrum in his right shoulder on Oct. 6, months after he agreed to a $55 million contract extension. He was injured in the team's first preseason game at Orlando on Oct. 3 when he landed awkwardly on the shoulder.
Kidd-Gilchrist played in 55 games last season, averaging a career-high 10.9 points, 7.6 rebounds and 1.4 assists in 28.9 minutes a game.
Coach Steve Clifford said there will not be strict minutes restrictions on Kidd-Gilchrist but that he would watch him carefully. The Hornets trailed by as many as 20 points against the Blazers but rallied back to single digits.
"I thought he'd be able to play six to eight minutes a time," Clifford said. "In the fourth quarter, when that group got rolling, I just told him to let me know."
Kidd-Gilchrist said he got tired in the third quarter.
"I was a little winded. I had a spurt of sprints up and down the floor so I got a little tired," he said.
The Hornets can use him. They have been beset by injuries this season. Nicolas Batum recently missed seven games because of a right toe sprain but returned for Wednesday night's 102-73 loss at Utah. The toe gave him trouble in Portland, and he finished with three points and eight assists.
"My toe is like three times bigger than the other one," Batum said.
Jeremy Lin injured his right ankle, which gave him trouble earlier in the season, in the loss to the Jazz and wasn't available Friday against the Blazers. Clifford said he had no timetable for Lin's return.
Charlotte also was without guard Jeremy Lamb for the fourth straight game because of a sprained big toe on his right foot.
