Mavericks' Cooper Flagg (shoulder) upgraded to questionable for Monday at Heat. Caleb Martin (thumb) doubtful. Out for Dallas are Santi Aldama (knee), Tarik Biberovic (heel), Dereck Lively II (foot) and Naji Marshall (illness).

The Mavericks are now expected to soon rule out Kyrie Irving as well from tonight’s home opener … which would mean no Irving or Cooper Flagg for San Antonio’s visit.

Cooper Flagg did not start the third quarter after Aaron Nesmith hit him on the shoulder. He did not return. 'They say' left shoulder soreness and called it precautionary. The Mavs host noted Flagg dealt with left shoulder issues last year and the home opener is tomorrow.

- The Mavs started Kyrie Irving, Max Christie, Cooper Flagg, PJ Washington and Daniel Gafford, the same starting group as in game one. at 10:42
- The host tied that substitution to the idea of playing Cooper with two other ball handlers, here Kyrie and Naji Marshall. Slightly later said he wants to see how the staff tinkers with that. at 36:58
- Gafford played only about 14 minutes but had five assists; the host said they used him as a hub. Cooper played only 17 minutes. at 3:42:17
- Just before halftime, Cooper Flagg was fouled hard in transition and was seen holding his shoulder. Postgame recaps say Aaron Nesmith hit him and he fell on his left shoulder. at 1:32:44
- The hosts said Flagg's left shoulder has been a recurring issue going back to last year, but one host did not think he has ever missed games for it. at 3:10:42

- An update the hosts read in the third quarter said Flagg would not return, with left shoulder soreness. The source of the update was not named. at 2:12:39
