"I think it's kind of freakish that it happened to the same guy in the same game against the same opponent," coach Ken Whisenhunt said on Monday.
Berry made the Pro Bowl and led the NFC in sacks in 2004, but has battled injuries since. He was being examined on Monday to determine the extent of the injury. Berry also missed the last eight games of the 2005 season with a torn pectoral muscle.
Through nine games this season, he has 21 tackles, 17 solo, and two sacks.
"Whatever the extent of it is, it's unfortunate that he has to deal with that because he worked very hard to get back this year and he's done an outstanding job for us," Whisenhunt said.
Joe Tafoya and Darryl Blackstock will share Berry's job.
