The final injury reports are in for Thursday night’s Warriors at Suns matchup at PHX Arena, and both sides will juggle key absences and late calls. Phoenix entered at 14–12; Golden State at 13–14. With both clubs hovering around .500, availability tilts matter, and tonight’s sheet offers a few that could shape rotations, spacing, and defensive assignments.

Warriors injury report: Horford out again, Spencer sidelined

Golden State will be without veteran big Al Horford, who is out with right sciatic nerve irritation. Per the report, this marks his ninth missed game in the last ten. The team also listed Pat Spencer as out (personal reasons).

The Warriors will turn to internal help in the frontcourt. With Horford out, Quinn (Quentin) Post is expected to take on a larger bench role backing up Draymond Green. That adjustment matters for Golden State’s second-unit shape and minute staggering around their leaders.

As the official league document notes: “Horford, Al. Out. Injury/Illness – Right Sciatic Nerve; Irritation.” The final NBA injury report, timestamped 12/18/25 at 1:30 p.m., corroborates Golden State’s listings.

“Post behind Draymond could swing the second-unit battle.”

Suns injury update: Jalen Green out; Allen, Livers questionable

Phoenix will again be without Jalen Green, who was ruled out with a right hamstring strain suffered on Nov. 8 against the Clippers. The team also listed Grayson Allen as questionable with right knee soreness and Isaiah Livers as questionable with a right hip strain.

There’s a bit of good news: Jordan Goodwin is available despite a jaw sprain and will play with a protective mask. Koby Brea remains out on a two-way (G League) designation, per team injury listings referenced in supporting articles.

The league file matches the team’s updates: “Allen, Grayson. Questionable. Injury/Illness – Right Knee; Soreness.”

• Jalen Green — Out (right hamstring strain; sustained Nov. 8 vs. Clippers)
• Grayson Allen — Questionable (right knee soreness)
• Isaiah Livers — Questionable (right hip strain)
• Jordan Goodwin — Available (jaw sprain; wearing a mask)
• Koby Brea — Out (two-way, G League)

“If Allen sits, who guards Steph from the jump?”

Why Grayson Allen’s status matters for Suns spacing and matchups

Allen has been described as a regular starter for Phoenix when active, and that matters on two levels. First, he impacts spacing around Devin Booker by stretching the floor. Second, he helps with defensive matchups on the perimeter. Against Golden State, that often means taking shifts against Stephen Curry or helping the Suns keep their matchups balanced.

If Allen can’t go, Phoenix loses a trusted piece that settles both the opening group and the early second unit. That would push more decision-making onto role players and could change how the Suns line up in the first six minutes of each half. If he is cleared, the starting five gets its familiar shape, and Phoenix’s half-court spacing looks more natural from the tip.

Jalen Green out: who fills the backcourt minutes?

With Jalen Green ruled out again, the Suns may lean more on Collin Gillespie next to Booker. That combination offers another ball-handler and steady guard play to keep the offense organized, especially in the non-Booker minutes. The report also notes Goodwin is available despite the jaw sprain, which gives coach optionality for defense, energy, and secondary creation, even if he’s masked.

Put simply, Phoenix’s backcourt plan tonight rides on two tracks: who starts (Allen’s call) and who soaks up the Green minutes (Gillespie/Goodwin). If the choices click, the Suns can keep their spacing and rhythm close to normal.

“Gillespie next to Booker is safe, not flashy—but it keeps the wheels turning.”

Golden State’s frontcourt shuffle without Horford

For the Warriors, Horford’s ninth absence in ten games has become a rotation reality. Post stepping into a larger reserve role behind Draymond Green is the immediate fix. That keeps Golden State’s defensive voice on the floor while offering another look off the bench.

It’s also a test of continuity. With Pat Spencer out, the Warriors lose another guard depth option, making their margin thinner if foul trouble or an injury pops up during the game.

• Al Horford — Out (right sciatica; 9th missed in last 10)
• Pat Spencer — Out (personal reasons)
• Quinn (Quentin) Post — Expected to play a larger bench role behind Draymond Green

Records, recent form, and what’s at stake

Phoenix came in at 14–12 after a home loss to the Lakers on Sunday, when Devin Booker scored 27 and Mark Williams added 20. Golden State entered at 13–14. These are two teams trying to stack wins and push above the mid-table clutter before the calendar turns.

That’s why these injury details matter. For Phoenix, the Allen decision is a swing variable for spacing and defense. For the Warriors, the Horford absence keeps the frontcourt in patchwork mode and increases the importance of early bench minutes from Post.

What to watch at tipoff

• Allen’s status near game time. If he plays, Phoenix’s starting shape and spacing look closer to full strength. If not, rotations shift right away.
• Backcourt balance without Jalen Green. Does Gillespie stabilize the offense next to Booker? How much can Goodwin give with the mask?
• Golden State’s second unit. Can Post’s minutes behind Draymond keep the Warriors steady when the starters sit?

As one source put it: “Horford has been ruled out due to sciatica, marking his ninth absence in the last ten games.” And on the other side: “Green has been ruled out due to a right hamstring strain that he sustained against the Los Angeles Clippers on November 8.” Those two lines set the table. The rest comes down to execution, timely shooting, and which questionable tag flips to available.

Final note: the official NBA injury report (12/18/25, 1:30 p.m.) matches these listings for tonight at PHX Arena. In a tight Western race, even one status change can tilt a game. Keep your eye on the pregame updates—that’s where the first big break might arrive.
