The Chicago Bulls and Lauri Markkanen are unlikely to agree to a contract extension before Monday evening's deadline.

Sources tell K.C. Johnson of NBC Sports that "the gap remains wide" as "talks on his rookie extension continued Sunday but sputtered on life support."

Markkanen previously told reporters he planned to pressure his agent to get a new deal done.

The 2021 free agency class has thinned out dramatically due to a number of high profile extensions, but many rival teams are expected to have ample cap space to pursue a player like Markkanen.
