  • Portland evened its best-of-seven series with San Antonio at one game apiece on Tuesday
  • Worse for the Spurs, Victor Wembenyama exited Game 2 with a head injury
  • See the updated Trail Blazers vs Spurs series odds

The Portland Trail Blazers went into Tuesday night dead in the water, at least according to oddsmakers. Already down 1-0, Portland was a +475 underdog to win Game 2 and a +3200 longshot to win their best-of-seven series with the San Antonio Spurs.

A few short hours later, how the tables have turned … or at least partially rotated. Portland won Game 2 (106-103) and Spurs’ All-Star Victor Wembenyama left with a head injury and entered concussion protocol.

That series of events led to Portland’s odds improving drastically.

Portland is now trading at 19¢ to win the series, which is equal to +426 odds. Yes, the Blazers are still a longshot, but those odds are six-times better than their odds ahead of Game 2.

San Antonio, meanwhile, faded from a roughly -3300 (97¢) lock to a -456 (82¢) favorite.

Heavy chalk? Certainly. Inevitable? Far from it.

Will Wembenyama Play in Game 3?

At this point, that’s not clear. The 22-year-old suffered a concussion in the second quarter of Tuesday’s loss after hitting his head on the court. He left and did not return, entering the league’s mandatory concussion protocol.

Concussion protocol requires at least 48 hours of inactivity followed by clearance from a doctor before returning to the court.

The good news for San Antonio is that Game 3 in Portland isn’t until Friday.

Wembenyama had a game-high 35 points in San Antonio’s 111-98 Game 1 rout, going 4-of-5 from three while also adding five boards and two blocks.

Stephon Castle had a team-high 18 points in Tuesday’s loss, going just 7-of-20 from the field. San Antonio was +7 on the glass in Game 1 and -1 in Game 2.

Despite the injury and the series shifting to Portland, Kalshi’s opening odds for Game 3 list the Spurs as slight 52¢ favorites (equal to -108 odds) with Portland at 50¢ (+100 odds).

Traditional sportsbooks have the odds skewed even more heavily to the road team.
