Boston Celtics center Jermaine O'Neal sat out his second straight practice Monday with a tight left hamstring, an injury coach Doc Rivers said will keep him sidelined for the rest of the week as a precautionary measure.

He also expressed a desire to participate in the approaching exhibition slate in order to develop on-court chemistry with his new teammates.

Rivers dubbed the guard day to day and suggested he could be back on the court as early as Tuesday. Read more: http://sports.espn.go.com/boston/nba/news/story?id=5648978
