A person with knowledge of the situation says that Chris Bosh of the Miami Heat will miss Sunday's All-Star Game with a calf injury, and has been replaced on the Eastern Conference roster by Atlanta's Al Horford.

That also means Bosh will not take part in the three-point contest on Saturday. The person spoke to The Associated Press Friday on condition of anonymity because neither the team nor the NBA had announced the moves.

Bosh's withdrawal and Horford replacing him were first reported by Yahoo Sports. Bosh's agent, Henry Thomas, did not return messages seeking comment.

Bosh did not mention the injury during Friday's All-Star media day availability session. He said earlier Friday that he was looking forward to playing in Toronto, where he spent his first 7 NBA seasons.
