An MRI on Thursday revealed "no significant damage," according to Mink:
"Nothing serious with Haloti," Harbaugh said. "There are some things in there we'll just have to see. It won't be anything that should keep him out of training camp or anything like that."
Albert Breer later reported the injury as an MCL sprain and that no surgery is required.
Ngata was hurt in the third quarter of Sunday's 34-31 win over the San Francisco 49ers in Super Bowl XLVII. Ngata was injured on a 6-yard touchdown run by Frank Gore. Ngata left the game and did not return.
After the game it didn't appear that Ngata was badly injured. NFL Network's Ian Rapoport reported that Ngata said he felt a lot better afterward. He was also seen jogging to his hotel room after the game, according to USA Today's Lindsay Jones.
Ngata is a four-time Pro Bowler who has spent all seven NFL seasons with the Ravens. The two-time first team All-Pro recorded 50 tackles and five sacks in 14 games this year.
