Ingram, a junior, was hurt during practice two days ago and his status will be evaluated on a week-to-week basis, Alabama coach Nick Saban said in a statement.
“It was a situation where everyone involved thought it would be better to take care of now, so he would not have any issues with it later in the season,” Saban said.
Alabama, which won college football’s national championship with a 14-0 record last season, hosts San Jose State on Sept. 4 and then is home to Penn State next week.
“Mark will definitely be out for this week’s game,” Saban said. “We will make every decision in the future based on what’s best for Mark and his career. This is not an injury that will affect Mark’s future ability to make a full recovery in a relatively short time frame.”
Ingram last season became the first member of the Crimson Tide to win the Heisman Trophy as the sport’s outstanding player. He rushed for 1,542 yards and 15 touchdowns during the season and then scored two more touchdowns in Alabama’s 37-21 win over Texas in the Bowl Championship Series title game.
