Cooper Flagg's Shoulder Sprain Ruins the Mavericks' Home Opener

The Dallas Mavericks are officially throwing a welcome-home party without the guest of honor. According to Marc Stein, Cooper Flagg underwent an MRI that revealed a mild left shoulder sprain, officially ruling him out for tonight’s home opener against the San Antonio Spurs.

If you bought premium tickets expecting to see the franchise cornerstone put on a show against an in-state rival, congratulations. You just paid a luxury tax to watch a rotation scramble. Flagg will be re-evaluated next week, which is the medical staff's polite way of saying you should probably find a new hobby for the next few days.

"Marc Stein reported the official MRI results and timeline."

The injury stems from a flagrant foul by Aaron Nesmith during the Mavericks' 121-105 road win over the Indiana Pacers. Flagg took a hard hit and did not return for the second half, leaving Dallas fans to collectively hold their breath while directing an entirely predictable amount of internet rage at Nesmith.

Before getting knocked out of the game, Flagg was putting on an absolute clinic. He racked up 14 points, five rebounds, six assists, and three blocks in just the first half. That is the kind of stat line that makes fantasy managers weep when a guy gets ruled out at halftime.

This is not entirely new territory, as Flagg dealt with a left shoulder issue during his rookie campaign. Shoulders are notoriously tricky, and when a guy has a history with the exact same joint, the training staff is going to treat him like a museum exhibit. Nobody is rushing him back for a random October game.

For anyone looking at the board tonight, Flagg’s absence completely scrambles the math for Dallas against San Antonio. Taking away a guy who can casually dominate both ends of the floor means the entire defensive scheme and offensive usage rates have to be rewritten on the fly.

Head coach Dusty May now has to figure out how to patch the rotation for the home crowd tonight and likely for the upcoming road trip to face the Miami Heat. Until that re-evaluation happens next week, Mavericks fans will just have to survive on the memory of that first half in Indiana.
