Sources -- Chicago Bulls' Zach LaVine to see specialist for ailing left knee

Chicago Bulls All-Star guard Zach LaVine is traveling to Los Angeles to get further evaluation on his left knee, but still hopes to participate in next Sunday's All-Star Game, sources told ESPN.

LaVine has been experiencing discomfort in the knee for several weeks, and although a January MRI showed no structural damage, there's certainly a level of concern within the organization, sources said.

LaVine was chosen to his second All-Star Game this season, averaging 24.6 points, 4.9 rebounds and 4.5 assists. LaVine and fellow All-Star DeMar DeRozan have been the league's highest scoring partnership this season, averaging 52.3 points, according to ESPN's Stats and Information.

LaVine appeared to struggle through Friday's victory over Minnesota, shooting 5 of 14 and noticeably wincing on the floor. LaVine sat out Saturday's victory over Oklahoma City on a back-to-back and consecutive games last week against Indiana and Philadelphia. He will miss games on Monday and Wednesday ahead of the start of the All-Star break, sources said.

The Bulls are withstanding numerous injuries to the backcourt this season, including Lonzo Ball (meniscus tear) and Alex Caruso (fractured wrist) who are out several weeks after surgeries. The team also lost forward Patrick Williams to a wrist injury early in the season, although he's expected to return this year.

Through it all, the Bulls are 36-21, one game behind first-place Miami in the Eastern Conference standings.
