CLEVELAND (AP) -- Cavaliers rookie center Tyler Zeller has returned after missing four games with a fractured left orbital bone and a concussion.

Zeller, who is averaging 7.5 points and 4.5 rebounds, entered Saturday night's game against Dallas with 5:54 remaining in the first quarter. He was wearing a mask to protect the broken bone.

Zeller was elbowed in the face by Los Angeles Clippers center DeAndre Jordan on Nov. 5. He scored a career-high 15 points and grabbed seven rebounds against the Clippers before he was injured.

Zeller was selected by the Mavericks with the 17th pick in the first round and then traded to the Cavaliers on draft night. He played college ball at North Carolina.
