During the heated Chicago Bulls practice on Monday, center Robin Lopez made an aggressive play on point guard Kris Dunn and the two began to exchange words, according to Malika Andrews of ESPN.

Robin Lopez briefly left the practice for about 15 minutes to cool off. When he returned, the seven-footer apologized to his teammates.

Losing is taking its toll on the Chicago Bulls. During the team's Monday practice in Santa Monica, Robin Lopez made an aggressive play on Kris Dunn, leading the two to exchange words. Lopez, seemingly angry, left practice for 15 minutes to cool off before returning.

The Bulls are a walking disaster right now. They have lost seven games in a row and are 10-33 on the season. Chicago is tied with the New York Knicks for the second-worst record in the Eastern Conference.

Robin Lopez didn't speak to reporters after the practice, but Kris Dunn did. The Bulls' starting point guard said it wasn't a big deal at all, and that he and Lopez didn't throw punches at each other.

“Just practiced hard,” Dunn said, via Teddy Greenstein of the Chicago Tribune. “(Robin is) my guy. He knows that. Every day it gets chippy, know what I'm saying? We've been losing a lot, so we're coming in and practicing harder.

“Trying to get that monkey off our back.”

The Bulls will look to end their losing streak on Tuesday against the Los Angeles Lakers, who will be without LeBron James.
