Celtics head coach Ime Udoka said Sunday that Johnson won't be re-signed to a second 10-day deal after the veteran's contract expired Saturday, Gary Washburn of The Boston Globe reports.

Udoka left the door open for Johnson to potentially rejoin the Celtics at a later date if the league awards the team another hardship exemption, but for now, the 40-year-old's unexpected return to the NBA will end after he made just one two-minute appearance with Boston on Dec. 22. The brief stint with the Celtics marked Johnson's first NBA action since the 2017-18 season, when he suited up in 55 games between the Rockets and Jazz.
