Ings clutched his left knee after a challenge by Villa substitute Trezeguet. A scan showed damage to his meniscus, Hasenhüttl said Wednesday at a news conference ahead of Friday’s match against Newcastle.
The knee was swollen and painful when Ings tried jogging on Tuesday, Hasenhüttl said.
Ings has been slowed by knee injuries in the past, but Hasenhüttl said this problem is unrelated.
Ings had a career-best 22 goals last season and was a substitute for Gareth Southgate in England’s 1-0 win over Iceland in the Nations League on Sept. 5. He scored in England’s 3-0 victory over Wales this month.
Southampton is fifth in the Premier League with 13 points after seven games.
