The Hawks were looking for frontcourt help in talks with teams in recent days and landed Ilyasova, who has been traded five times in the past three years. He is averaging 14.8 points and 5.9 rebounds in 56 games for the 76ers. He will be a free agent at the end of the season.
Splitter has been plagued by injuries over the past two seasons and has not played this season due to a calf injury. He is also on the final year of his contract.
The Hawks will send a future second-round pick and give the 76ers swap rights on another second-round pick as part of the deal.
