Sources: Hawks' Young (knee sprain) out 4 weeks

Atlanta Hawks star Trae Young sustained a sprained MCL in his right knee and will be reevaluated in four weeks, sources told ESPN on Saturday.

Young underwent an MRI on Friday, and multiple doctor reviews showed that he dodged major structural damage in the knee.

Young suffered the injury during the first quarter of Wednesday's win over the Brooklyn Nets. Young was standing underneath the basket when teammate Mouhamed Gueye was shoved by Nets forward Noah Clowney and fell backward into Young's leg.

Young left the team, which finishes a four-game road trip Sunday in Cleveland, to go back to Atlanta to undergo the MRI and see doctors.

Atlanta entered this season with heightened expectations after an impressive offseason that added Kristaps Porzingis, Nickeil Alexander-Walker and Luke Kennard.

The Hawks already needed time to develop cohesion with their new pieces but now will be without their star point guard for more than a month.

Jalen Johnson -- who is averaging 20.8 points, 8.2 rebounds and 5.0 assists -- said Young is "the best in the world" at being a playmaker and scorer. Replacing an All-Star who averaged 24.2 points and 11.6 assists last season will require a team effort.

"It's going to take time," Johnson told ESPN. "But we're all disciplined. Everybody works hard. Everybody's willing to listen. We take our film sessions very seriously. So I think if we just continue to grow after each game and go out there with a winning mindset, everything will take care of itself. Just not putting too much pressure on ourselves and feel like we have to overdo something."

The reigning assists champ, Young is averaging 17.8 points and 7.8 assists this season.
