"It's already swollen and bruised and, with a couple of days in between [games], I don't want to go out there and make it swell up," Crosby told local reporters Monday. "I just want to get the swelling down and make sure it's ready for Wednesday [against Montreal]."
Crosby, who said he intends to play Wednesday, hurt the foot while blocking a shot by Anaheim defenseman Francois Beauchemin in Saturday's 5-4 victory over the Ducks.
Local reports said X-rays didn't detect any fractures in the foot.
"It was a different foot, so I didn't think it was the same thing," Crosby told reporters. "There was pain there, so obviously something went through my mind, but the X-rays were negative so that's a good sign."
Thoughts automatically turned to the spring, when Crosby played the final weeks of the season and playoffs with a stress fracture in his left foot. The Penguins didn't reveal that injury until after they were eliminated in the first round by the Ottawa Senators.
