THURSDAY, 2:20pm: The Celtics have officially re-signed Randolph, the team announced in a press release. The release refers to it as a multiyear deal, which likely means, as Charania reported, that it will be guaranteed for this season and non-guaranteed for next season.
WEDNESDAY, 2:41pm: Randolph's deal with the Celtics will include a team option for next season, tweets Shams Charania of RealGM.com.
11:25am: The Celtics officially signed D.J. White for the remainder of the season today, and will do the same tomorrow with another player whose second 10-day contract will expire. Head coach Doc Rivers told Gary Washburn of the Boston Globe (Twitter link) that, in the interest of continuity, Shavlik Randolph will be re-signed to a rest-of-season deal.
After not playing during his first 10 days with the club, Randolph has appeared in three contests during his second 10-day deal. His best performance came last Saturday in a 105-88 win over the Bobcats, as he piled up six points, eight rebounds, a pair of steals in just over 15 minutes of action. Prior to making his NBA return with Boston, the big man appeared in 28 games for the Foshan Long Lions in China, averaging 32.0 PPG, 14.6 RPG, 1.4 APG, 1.7 steals, and 1.0 blocks in 36.5 minutes per contest while shooting 53.1% from the floor.
Once they formally announce their rest-of-season deals with White and Randolph, the Celtics will have 15 players under guaranteed contracts. So if the team wanted to add another player before season's end, a corresponding roster move would be necessary to open up a spot.
