The team announced Monday that Jenkins underwent surgery on his lower back and with rest and rehabilitation, will miss the remainder of the season.
Jenkins hasn't played in a game since Dec. 20.
Taken 23rd overall in 2012, he had a promising rookie averaging 6.1 points in 61 games while shooting 38.4 percent from 3. Coming into this season, he was seen as a potential valuable piece to the Hawks depth.
The second-year guard appeared in only 13 games this season, averaging 3.1 points and 1.7 rebounds in 12.2 minutes.
