Hawks all-star forward Al Horford will miss the next three to four months with a torn pectorals major, the large chest muscle attached to the left shoulder.

In a statement released by the Hawks, the organization said this type of injury usually requires surgery, but Horford "will get a second opinion and make a final decision at that time."

"We are very disappointed for Al and our team and we wish him the best as he moves forward in the rehabilitation process," said Hawks' Executive Vice President and General Manager Rick Sund.

"He has contributed greatly to our success since his arrival in Atlanta, and that's evident by his selection to the NBA's All-League team last season (third team pick)."

Channel 2 sports director Zach Klein broke the story on Twitter with a league source telling him Horford was "pretty much done for the year."
