Georgia hired Alabama defensive coordinator Kirby Smart as its new head coach, replacing Mark Richt, who won two Southeastern Conference titles and nearly 75 percent of his games in Athens but fell out of favor with many top boosters because of a perception that his teams underachieved.

Smart, who turns 40 om Dec. 23, played at Georgia in the 1990s and has been Nick Saban's defensive coordinator at Alabama since 2008. He was expected to remain at Alabama through the College Football Playoff.

• South Carolina officially announced Will Muschamp, 44, will be its next coach, replacing Steve Spurrier, the program's leader in victories. A news conference is scheduled for Monday. Muschamp spent this past season as Auburn's defensive coordinator after being fired after four seasons as head coach at Florida.
