Stars from several different sports took to Twitter on Friday to try and cope with the school shooting in Connecticut, and the NFL asked each of its teams to observe a moment of silence before this weekend's games to pay respect to the victims.
A man opened fire at an elementary school where his mother was a teacher, killing 26 people, including 20 children. The 20-year-old killer, carrying two handguns, committed suicide at the school.
Miami Heat star LeBron James said he was "sick" and the shooting was "really messing with my mind" in a series of posts on Twitter.
Boston Celtics coach Doc Rivers said it was "just an awful day." Cleveland Cavalier coach Byron Scott, struggling to stay composed, said the tragedy had affected him.
