Sidney Crosby was injured in the first period of the Pittsburgh Penguins' preseason finale Saturday.
The center played 6:42 in the first period against the Buffalo Sabres but did not play the final two periods. Pittsburgh forward Bryan Rust left the game after he was injured in the third period.
"They both got hit with shots," Penguins coach Mike Sullivan said. "They are being evaluated now. We will probably have more definitive answers tomorrow morning."
