Complaining of a headache and saying that he felt light-headed, Jacobs was taken by ambulance to St. Mary's hospital in Athens after practice Wednesday night and was transferred to Atlanta's Emory Medical Center Thursday afternoon.
The symptoms did not occur until after practice ended Wednesday.
"It got to the point where (Georgia director of sports medicine) Ron (Courson) and I thought we should do something about it," said Coach Mark Richt of the decision to call for an ambulance. "We just don't know exactly what's going on, what caused it."
Jacobs was listed in stable condition at Thursday night at Emory, where he will undergo further neurological evaluation.
Jacobs will not play in Saturday's 12:30 p.m. ET game at Mississippi. Though the loss of the line's most experienced player is a devastating blow to a unit which recently lost another senior starter, defensive end Bruce Adrine, the critical depth problem was not the primary concern as coaches worried about Jacobs' health.
"(The starting lineup) is not on my mind right now,'' said defensive line coach Rodney Garner Thursday. Garner and Courson were with Jacobs as he was taken out of the Georgia locker room on a stretcher Wednesday night.
Jacobs, from Atlanta's Westlake High School, has started all eight games and ranks fourth on the team with 55 tackles, including team-leading totals of 10 tackles for lost yardage and 21 quarterback pressures.
Jacobs became dehydrated in last week's loss to Auburn and had to return to the locker room after halftime for more liquids. He returned later in the game.
It was not known if there is a connection between the problem Jacobs experienced in the game and his symptoms that caused him to be hospitalized.
Richt visited Jacobs at St. Mary's hospital Wednesday night and was concerned that the cause of Jacobs' symptoms had not been found.
"Anytime any of your players are not well, you're concerned about it," Richt said, adding "You could tell he was scared."
Richt said Josh Mallard, returning from a sprained knee, will be "good to go '' this week. Johnathan Sullivan, who moved from tackle to defensive end last week to compensate for the losses of Adrine and Mallard, may play both positions this week. Freshman David Pollack, who made his first start last week, likely will start again at defensive tackle.
If Sullivan starts at defensive end, it is possible Pollack and sophomore Ken Veal would be the starting tackles. Like Sullivan, Mallard can play at tackle or end.
Richt said Georgia will need Shedrick Wynn, a sophomore, to play more minutes as a top backup at tackle.
Georgia practiced at Sanford Stadium Thursday and will leave today for Saturday's game.
