CHICAGO - Cleveland Cavaliers point guard Kyrie Irving is hurting more than he is letting on.

He's dealing with more than just the right foot strain made public by coach David Blatt on Friday, one that occurred almost three weeks ago in Game 2 of the first-round series against the Boston Celtics.

After the huge Game 4 victory over the Chicago Bulls to even the series, I asked him directly in the media scrum to address if there's anything wrong with his left leg, and he paused briefly, before responding "Nah. Nah, there's nothing wrong."

As soon as the media contingent dissipated, Irving said, "Chris, you're very observant."

Irving's left leg has been wrapped in dynamic taping, which is elastic that helps support the structure of the body. The pain is believed to be caused due to overcompensating.

Upon exiting the arena last night with a grimace plastered to his face, Irving walked gingerly and limped noticeably. However, it wasn't his right foot that he was favoring. He was very cautious with each step not to place weight on his left leg. The Cavaliers are calling it a "sore left leg" for the time being.

Considering Irving's right foot never fully healed despite an eight-day layoff following the opening series, this may be something he has to play through the postseason.

Irving is guarded when it comes to revealing injuries, not wanting to give the opponent any sort of an advantage. He said "that's Basketball 101."

He's laboring out there. The speed, the acceleration, the first step isn't there. He's giving it all he has, determined not to let his team down.

"I'd rather will it out and give it a chance, than sitting back and watching my brothers compete without me," he said.

Update: Kyrie Irving underwent an MRI Monday morning on his left leg and it revealed tendonitis in his left knee. He will play in Game 5 on Tuesday at The Q.
