Dan Hipsher, the Tide's associate head coach under Grant during 2009-13, was hired as Texas-Pan American's head coach in April. That led to the shuffle of responsibilities announced Monday.
Grant said John Brannen has been promoted to associated head coach. Brannen has served as an assistant coach the past four years.
Pettway was Alabama's director of basketball operations the past three seasons. Before that, he was an assistant coach at Alabama during 2008-10 and Jacksonville State during 2006-08.
“Antoine’s done a great job for us,” Grant said. “I think he has really grown as a coach and has prepared himself to take that next step in the coaching career. He knows what it takes at this level and I am confident that he’ll step in and make a smooth transition as an assistant coach.”
As a player, Pettway was part of Alabama's 2002 SEC championship squad and the 2004 team that went to the NCAA regional finals.
“I am extremely grateful that Coach Grant has the confidence in me to give me this opportunity,” Pettway said. “Coach Grant is a great mentor and leader. I have learned a great deal observing him, our players and coaches and I will work diligently to have a positive impact on our student-athletes and our program. I love the University of Alabama, our fans and the city of Tuscaloosa, and I am eager to get going.”
In addition, Grant announced Lou DeNeen will be the program's new strength and conditioning coach. He spent the past six years at UAB. He also was at Florida International (1991-94, 1997-2007) and California (1994-97).
