The Celtics had a deadline of today to decide if they would retain Demetrius Jackson and guarantee his full salary for the year or to waive him and remove $650,000 off the books. It appears that they elected to release him.
Celtics to waive Demetrius Jackson, avoid paying his $650,000 guarantee. His initial indication is he'll likely not play in SL game tonight.

This likely paves the way for the team to sign Guerschon Yabusele and Semi Ojeleye. The team has already signed Abdel Nader (according to reports and Nader’s instagram account).
