Judge Amy St. Eve told attorneys at a hearing Friday that she'll sentence Tony Rezko on Oct. 21.
Rezko's attorneys and prosecutors had asked the judge earlier to delay Rezko's sentencing to allow for the possibility he could testify at two upcoming trials, including Blagojevich's corruption retrial in April.
At Friday's hearing, the defense also argued in favor of a new trial for Rezko based on a U.S. Supreme Court ruling scaling back so-called honest services laws.
The judge didn't immediately rule on the motion.
Rezko is in jail and didn't attend Friday's hearing. A jury convicted him in 2008 of squeezing kickbacks from people seeking state business.
