Cleveland, OH -- (Sports Network) - Cleveland Cavaliers big man Ben Wallace is being listed as doubtful for Game 3 in the team's Eastern Conference semifinals series versus Boston set for Saturday.

Wallace, who was forced out of Thursday's Game 2 matchup with bouts of dizziness, was diagnosed with a viral inner ear infection. The Cavs lost the game 89-73.

Wallace left early in the first quarter and nearly collapsed after walking toward his bench.

The defensive standout was taken to the locker room to be examined. He did return to the Cleveland bench for a bit in the second quarter but was still feeling dizzy and ruled out for the game.

After the contest, Wallace blamed his problems on allergies.

"It started as an allergy attack," Wallace said. "It was just a headache, then I got dizzy. You know it's (Boston) a tough place for allergies, but no one warned me."

Exams and testing done at The Cleveland Clinic on Friday determined that Wallace has allergies and a viral inner ear infection in his left ear with dizziness.
