But the Pittsburgh Penguins star and his coach said they would rather be safe than sorry on returning to games, according to the team website.
Crosby met with Dr. Michael Collins and took an ImPACT test on Wednesday when he didn't feel well and had a slight headache after practice, coach Dan Bylsma said, according to the team's website.
"Dr. Collins said there is no indication of a concussion at this point in time," Bylsma said.
But Crosby, who missed much of last season and the opening weeks of this season with post-concussion symptoms, said he's just trying to be careful, according to the website. Crosby will sit out Thursday night's game at Philadelphia and Saturday's game at the New York Islanders.
"I just want to be smart with this," Crosby said. "It's been a long road back and we want to err on the side of caution.
"I've taken some good hits over the past few weeks and am happy with the way my body responded, but after discussing things with doctors it was better to make sure I was cautious before returning to play."
"It was not a one-time incident in the game. He took a couple hits in the game and didn't feel 100 percent after the game, so that was an indication," Bylsma said.
Crosby's ImPACT test "was exactly what it was when he returned to play," Bylsma said, according to the report.
