Also worth passing along: Word is Dylan Harper might be ahead of schedule in his return from thumb surgery. He won't play tonight, but would not be surprised to see him in action at some point before the preseason slate ends.

In addition to Castle (knee), the Spurs will also be without Fox (hamstring), Harper (thumb), McLaughlin (hamstring), Sochan (calf), Olynyk (heel) and Vassell (healthy scratch). Vassell is expected to play at Miami on Wednesday, though.

Stephon Castle is day to day and out for tonight’s preseason opener with a bruised knee after his collision with Wembanyama in Saturday night’s scrimmage. Nothing serious, just a precaution, the Spurs say.

Pop is in attendance at shootaround this morning, enjoying a chat at the moment with Sochan.

Kelly Olynyk did not participate in practice, doing only work on the side as he continues to rehab after undergoing surgery on his left heal in April. He is expected to return at some point in the preseason and be ready for the season opener.

Spurs Re-Sign Bismack Biyombo, Waive Isaiah Miller open.substack.com/pub/thespotu...

The Spurs waived Isaiah Miller to sign Bismack Biyombo.

The Spurs have officially re-signed Bismack Biyombo.

Biyombo will fill the Spurs’ 15th final standard roster spot. Before he can be signed, someone needs to be waived. The Spurs have a full roster of 21 players at the moment.

Last year, Isaiah Miller was signed with San Antonio for 2 days, then waived shortly after to be able to play in Austin. This could be a similar move to allow him to play in Austin next season, if he gets waived again. open.substack.com/pub/thespotu...
