Kris Humphries was heading for a quiet Saturday. The Cleveland Cavaliers were in town, and the matchups had the Celtics coaches preparing to use Vitor Faverani more among the large people in reserve.

But then it was learned that Andrew Bynum had angered his bosses to the point where he was denied an all-expenses-paid trip to Boston and suspended indefinitely.

So Humphries was the first player off the bench and provided 10 points, three rebounds and an assist in 17 minutes of a three-point win. He was needed and he was ready.

“High level of professionalism,” coach Brad Stevens said. “HIGH level.”

Walter McCarty knows it first hand. As the assistant coach who works with Humphries before games and after practices, McCarty imparts tips and generally gets a great workout himself with someone willing to go harder than most others.

“I’m not surprised when he goes in the game and plays well,” McCarty said. “If I’m ever in a conversation with Brad and he asks me how Kris is doing and what (are) his spirits and his work ethic like, I just tell him, ‘Kris is great. He’s been working. If you put him in, he’s going to be ready.’

“Brad paired me with him. It’s been great. We get along great, and we love working with each other. It’s been a pleasure for me working with him. I’ve known him over the years, but I’ve gotten the opportunity to really get to know him working with him. We have a lot of fun.”

Humphries has appeared in 23 of the Celts’ 30 games and provided gritty defense, good work on the boards and a nice outside touch — the four shots he hit Saturday were from outside the lane; his three misses were within it. The averages of 6.1 points and 4.3 rebounds per game are modest stuff, but a bit more impressive when you consider the numbers have come in just 15.6 minutes.
