Bulls power forward Bobby Portis revealed Saturday that he has been playing through a foot injury for the past two months after an incident with a heat pack. Portis said the injury occurred before a March 4 game against the Los Angeles Clippers. "The heat pack burned me before the game," Portis said. "I was actually on the [trainer's] table. I couldn't feel it. I had my headphones in, but I didn't feel [the pack] burn through. ... Ever since then, it's been hurting." Portis said that he didn't want to reveal the injury and risk losing his place in the rotation. Read more http://www.espn.com/nba/story/_/id/...ward-bobby-portis-played-3rd-degree-burn-foot
