Naughton landed on his head in sickening fashion after leaping for a mark during the third quarter of the Bulldogs' 18.18 (126) to 9.6 (60) thumping by Sydney on Thursday night.
The 26-year-old landed with serious force and lay motionless on the ground, before a stretcher took him from the field.
The Bulldogs are optimistic he has avoided a serious injury, but Naughton will undergo scans on Friday for a potential neck strain.
Remarkably, the club insists Naughton isn't even showing signs of concussion following the dramatic incident that shocked all watching at the ground and on TV.
However, there will be no reprieve for the wounded Bulldogs ahead of their clash with Fremantle next Friday.
Bulldogs coach Luke Beveridge revealed star defender Rory Lobb will miss up to a month with a hamstring injury.
"He got through a bit of training, felt OK, and he felt it in another spot, a bit lower down," Beveridge said,.
"We scanned it again, and something showed up as a bit risky.
"The initial signs were that he got a knock, bit of bleeding, but then in another spot, he had some discomfort, so he'll be out for a good month."
Lobb joins ruckman Tim English, star forward Sam Darcy and his fellow defender James O'Donnell.
Beveridge has ruled English (knee) out of returning to face the Dockers.
The Bulldogs will also be cautious with veteran midfielder Tom Liberatore, who is in the concussion protocols after a knock against Geelong.
After starting the season 4-0, including a stirring first-up win over reigning premiers Brisbane at the Gabba, the Bulldogs' campaign has dramatically altered course with three-straight heavy defeats.
"My message to the players was just we're here to support you," Beveridge said.
"We're here to look for the next best version of ourselves, and whether that's next week or in six weeks' time.
"But we've just got to deal with the injury toll.
"We've just got to encourage and help the boys believe that they're good enough to be in a winning Western Bulldogs team."
Superstar Marcus Bontempelli entered the match with a sore knee, but was still typically brilliant in leading the Bulldogs' charge in a losing cause.
"He charted his own course early in the week that he was going to play, and we did it a little bit differently," Beveridge said of Bontempelli.
"Because he was so positive about it, I didn't really think he wasn't going to play."
