What happened: Detroit Pistons center Jalen Duren is prohibited from participating in Monday's Media Day activities under league rules until he signs a new contract, according to a report. A source close to the process confirmed the restriction as the standoff continues.

Why it matters: The two sides are reportedly deadlocked over a $200 million dispute. Because Duren was extended a qualifying offer, he is additionally blocked from being traded until Jan. 15. The rule leaves the franchise with limited immediate avenues to resolve the situation.

What to watch: Watch for whether the Pistons and Duren can reach an agreement before the regular season begins.
