Chicago Bulls guard Zach Lavin has been brilliant in Sunday's win over the Utah Jazz, but head coach Billy Donovan can't help but worry about his superstar.

LaVine scored 26 points, five rebounds and five assists to lead the Bulls to an unbeaten victory over the then-unbeaten Jazz 107-99. His shots were also pretty good, 9-of-19, though he was dealing with a hand with a broken thumb.
However, Donovan claimed that Lavine was not behaving as he usually was because of his injuries. While he admitted he persevered in agony, the Bulls head coach was clearly worried.
Donovan shared: "I don't think he's himself. ”
In any case, Zach Lavin is not going to stop and rest as long as his physical examination is passed. He hinted at a slight tear in his ligament against the Toronto Raptors on Tuesday, and he held his foot even harder during Saturday's game.
Lavin reiterated that if he passes the medical examination, he will continue to play.
It's understandable why LaVine chose to play, injuries weren't his main shooter, so despite some limitations, he was still able to perform at a high level. The Bulls and their team doctors are also likely to prevent him from playing, which will exacerbate the problem if he is deemed unprepared.
On the face of it, despite the injury, Lavin seemed to be fine. Of course, no one will blame Donovan for his worries, because he himself knows that it's been a long season and it might be better to let this explosive defender rest and recover than risk a long injury.
