NBA Notes: Mavs, Luka Doncic, Celtics, Derrick White, Pelicans

Mavericks

Star guard Luka Doncic is expected to miss the Mavericks’ preseason finale with a mild left calf strain, coach Jason Kidd told reporters.

Kidd added that Doncic “will be reevaluated later this week.”

Meanwhile, Marc Stein of The Stein Line suggested the Mavs don’t suspect the injury is serious and the team is “optimistic” Doncic will be good to go for the season opener on Oct. 25.

• In case you missed it, Dallas has signed guard Taze Moore to its preseason roster. We have that full post here.

Celtics

The Celtics and guard Derrick White have been discussing a contract extension in recent weeks, per Adam Himmelsbach of the Boston Globe.

The sides have a week to decide, and it may take that long. Since White has two seasons remaining on his current contract, he can only be extended through the end of the offseason.

One thing’s for certain — he may become more important this season, as the Celtics traded away both Marcus Smart (Grizzlies) and Malcolm Brogdon (Trail Blazers).

Pelicans

• The Pelicans have waived Landers Nolley II and signed guard Izaiah Brockington, the team announced in a press release.
• Brockington is getting a second chance with the Pelicans — and G League’s Birmingham Squadron — after being forced to sit out last season with a torn ACL. He played for New Orleans in Summer League in July.
• Nolley went undrafted out of Cincinnati this past summer. He too is likely headed to Birmingham.
