After being out six months while recovering from back surgery Celtics forward Jared Sullinger didn’t know what to expect heading into the first day of training camp here Tuesday. He was as curious about his performance as others were.

The test results came back pretty positive too.

“Pleasantly surprised at his motor because I thought it was pretty good” coach Brad Stevens said.

Sullinger felt the same way: surprised.

“Yes very. I didn’t think I was going to make it through practice” he said. “Being six months off and then trying to get back in the swing of things that’s really really tough.”

Still Sullinger said he’s “not even close” when it comes to his conditioning. “I’m nowhere near where I need to be” he said.

He also said he’s “very rusty.” With what? “Everything” he said. “Timing footwork where I need to be on the court just trying to figure out what I can do. I had back surgery now I’ve got to modify some things and see what I can do well.”
