At some point this season the Cavaliers believe they will at long last have a deep and talented corps of players who can rotate at center.

That point became more distant in the future however when Tyler Zeller had an appendectomy Friday. The 7-foot second-year player already was recovering from a hip injury suffered during an intrasquad scrimmage. Now his return to the court is unknown. Zeller has been discharged from the hospital but his recovery will not be accelerated for the sake of basketball.

With fellow 7-footer Andrew Bynum still sitting out as he rehabilitates from March knee surgery – and no timetable on his return to 5-on-5 drills – the Cavaliers are down to a list of centers that features oft-injured Anderson Varejao and a bunch of guys fighting for a roster spot in training camp.

Henry Sims is among that group that also includes Kenny Kadji and DeSagana Diop. Although Diop has veteran experience and Kadji seems to have a scorer's touch judging from his 15 points in the preseason opener Sims has plenty to offer too.

The 6-10 Georgetown product is eager to help in whatever way possible.

"I feel like I'll do whatever's in my power to make it on this team" Sims said Sunday. "Coach (Mike Brown) wants defense I'm going to bring him defense. I'm going to do everything in my power."

Against Orlando on Friday Sims' defensive presence particularly against Magic center Nikola Vucevic earned post-game recognition from Brown on the 23-year-old's ability to impact the game – even though he had just four points and one rebound.
