Chicago ? Hee Seop Choi was resting at home Sunday, a day after a violent collision with Kerry Wood that left the Chicago Cubs first baseman with a concussion.

Choi still had a headache and his neck was sore, but he was in good spirits, Cubs manager Dusty Baker said.

Choi was placed on the 15-day disabled list before Sunday night’s game against the New York Yankees and has been ordered to rest for the next week.
