The Hawks announced that sophomore guard John Jenkins underwent season-ending lower back surgery this morning.
The 2012 first-round pick has been bothered by back issues for months now, but they most recently flared up with some leg nerve problems in late December, and he hasn't played since. He only managed to appear in 13 games during his sophomore season.
Jenkins will have a period of rest and recovery and will then undergo treatment and rehabilitation for his back. Best of luck for John in his recovery.
