After signing with the Atlanta Hawks this summer to play the backup point guard role for the team, 11-year veteran Jarrett Jack will not be ready for the start of the upcoming season.

The development was confirmed by head coach Mike Budenholzer on Tuesday.

Since signing with his new team, Jack has not been able to participate in any of their practices as he is continuing to recover from a knee surgery he had last January. He was diagnosed with a torn ACL during a game against the Boston Celtics.

No timetable has been set for his return yet but as it appears, there is significant progress to his recovery.

With the Georgia Tech product slated to miss significant time, Will Bynum and Malcolm Delaney are expected to compete for extended minutes as Dennis Schroder‘s backup at the one spot. And even after Jack’s return, he will be slowly eased back to the lineup as he shakes off some rust after missing the past nine months of basketball work.
