San Francisco 49ers running back suffered a concussion during the second half of the team's game against the Detroit Lions. He did not return to the game.

When asked about Gore's condition, head coach Mike Nolan said that it was a minor concussion.

According to Matt Maiocco's blog entry today, wide receiver Arnaz Battle fractured his hand in the game against the Lions. He is expected to be examined further tonight but felt that he would not miss any playing time.

"It's nothing major," Battle said.

Battle continued playing dispite the injury.
