CINCINNATI, Ohio -- Jarrett Jack, who has been held out of the last four preseason games to rest his sore left knee, will make his first start at point guard tonight against the Washington Wizards, coach Mike Brown announced after the morning shootaround at US Bank Arena.

Kyrie Irving will shift over to shooting guard in place of Dion Waiters, who will miss the game with an ankle injury. C.J. Miles is out with a sore right leg, and rookie Sergey Karasev is doubtful with a sprained left ankle suffered in the first half of Monday's game at Columbus.

Jack, who signed a four-year deal as a free agent last summer, is thrilled to be able to play again.

"It's good to be back,'' he said. "It was tough sitting on the side watching my guys. I'm just going through the process of building chemistry and camaraderie, trying to be as much of a coach and the best teammate as I can. But not to be on the floor, there was nothing else I could do.''

The eight-year veteran has been remarkably durable throughout his career. He played 79 regular-season games with the Golden State Warriors last season and all 12 playoff games. So what will he be trying to accomplish tonight?

"Just try to get my rhythm, just try to make sure I understand the offense, just be able to go up and down a little bit and just be able to respond,'' he said. "Hopefully I can do that a little bit and coach will let me play in the back-to-back tomorrow [at Charlotte]. He's been on me about taking it easy, it's a long season. But I'm not that type. I want to be out there battling, fighting with my guys every time we take the floor -- preseason or regular season. … That's just competitive nature.''

Probable starting lineups: Cavs -- F Tristan Thompson, F Earl Clark, C Anderson Varejao, G Kyrie Irving, G Jarrett Jack. Wizards -- F Trevor Ariza, F Trevor Booker, C Nene, G Bradley Beal, G John Wall.

Injuries: Cavs -- Rookie Sergey Karasev sprained his left ankle at Columbus on Monday and is listed as doubtful. Andrew Bynum (knees), Carrick Felix (sports hernia), C.J. Miles (sore right leg), Dion Waiters (sore right ankle) and Tyler Zeller (appendectomy) are out. … Wizards -- Emeka Okafor (herniated disc in neck), Otto Porter (right hip flexor) and Chris Singleton (left foot) are out.

Up next for Cavs: Thursday at Charlotte
