The Chicago Bulls have exercised their fourth-year option on forward Lauri Markkanen and the third-year options on center Wendell Carter Jr. and small forward Chandler Hutchison, the team announced in a news release.
All three now have their deals guaranteed through the end of next season.
Markkanen averaged 18.7 points and 9.0 rebounds in 52 games last season, shooting 43 percent from the field.

Hutchison also appeared in 44 games last season as a rookie, averaging 5.2 points and 4.2 boards.
