The Boston Celtics suffered two massive blows on Monday night. Not only did Boston lose Game 4 to the New York Knicks, putting them in a 3-1 hole and one game away from elimination, the C’s also watched leading scorer/rebounder, six-time All-Star, and three-time All-NBA First Teamer Jayson Tatum go down with a lower-leg injury.

With Tatum likely on the shelf for the remainder of the series and Boston one loss away from hitting the links, the Celtics vs Knicks series odds now heavily favor New York.

New York is now a -525 favorite to advance, needing just one victory in the next three games to move onto the East finals in the NBA playoff bracket. The Knicks’ odds give them an 84% implied win probability. Boston comes back as a +400 underdog (20% implied win probability) and a +240 underdog to even force a Game 7.

If the Knicks are able to knockout the defending champions, it will be one of the bigger upsets in recent NBA history. Boston opened as a -800 favorite to advance (88.89% implied win probability), while New York was a +550 longshot (15.38%).

After getting crushed in Game 3 at home, the Knicks answered back in Game 4 on Monday with a 121-113 win at MSG. Jalen Brunson (30.1 PPG, 4.0 RPG, 8.0 APG postseason) had a team-high 39 points and 12 assists while shooting 14-of-25 from the field (56%) and 4-of-8 from three.

Perhaps even worse for Boston is that Jayson Tatum (28.1 PPG, 11.5 RPG, 5.4 APG postseason) suffered what appeared to be a devastating leg injury. He was scheduled to undergo an MRI on Tuesday but many are speculating that his season is over.

Game 5 is scheduled for Wednesday, May 14, back in Beantown. The good news for the Celtics is that, at least this season, they’ve responded well when Tatum has been out of the lineup.

Boston went 8-2 straight-up in the nine regular-season games that Tatum missed, and took down Orlando (109-100) in Game 2 during the first round of the playoffs when Tatum sat with a bone bruise in his right wrist, though they failed to cover as double-digit favorites.

They also struggled against the number in the ten regular-season games without Tatum, going just 4-6 ATS despite the solid 8-2 SU record.

The Knicks vs Celtics Game 5 odds have already been released and appear to assume that Tatum won’t be in the lineup.

The NBA odds for Wednesday’s Game 5 at TD Garden list the Celtics as modest 4.5-point home favorites and -185 on the moneyline. I say that those odds assume Tatum won’t be playing because they significantly different from the odds for Games 1 and 2.

In Game 1, Boston was a 9.5-point home favorite and -400 on the moneyline. After their stunning Game 1 loss, Boston was an even bigger favorite in Game 2, laying 10.5 points against the spread and closing at -520 on the moneyline.
