Spurs Guard Stephon Castle Downgraded to Questionable with Migraine

Stephon Castle getting downgraded to questionable with a migraine is the exact kind of late-breaking update that ruins a perfectly good Saturday afternoon.

Underdog NBA reported the downgrade, leaving the 21-year-old San Antonio Spurs guard in limbo just hours before tip-off.

"Underdog NBA reported: 'Stephon Castle (migraine) downgraded to questionable Saturday.'"

Castle has already been through the physical wringer recently. Between a pelvic contusion, a hip flexor strain, and a left thumb sprain on his medical chart over the last year, adding a sudden migraine to the list feels like the basketball gods are just piling on.

A migraine is the ultimate wild-card injury on an NBA injury report. It is not a sprained ankle you can tape up or a bruised hip you can freeze into submission. It is your own brain deciding that looking at bright arena lights sounds like a medieval torture method.

Sportsbooks and daily fantasy apps hate this kind of uncertainty just as much as the fans do. When a key rotation guard goes from active to a coin flip, the entire game script gets thrown into a blender. You do not need to be a sharp to know that shifting usage rates will move the point spread and scramble player props before the ink is even dry.

We will not know his official status until San Antonio goes through pregame warmups and sees how he handles the noise. If the lights are too bright, expect the Spurs to pivot their rotation and leave Castle in a dark, quiet room to recover.
