The schools discussed rescheduling the game later in the season but were unable to do so because the teams do not share a mutual bye week.
"We are in complete agreement with the decision to cancel Saturday's game," Georgia Tech athletic director Todd Stansbury said. "While we're disappointed for both teams' student-athletes, coaches and fans, recovering from the effects of Hurricane Irma should be and is the top priority for UCF and the entire state of Florida at this time. We wish them the very best in their recovery efforts and look forward to meeting on the gridiron down the road."
The UCF campus in Orlando, Fla., will remain closed through Wednesday, the school announced Sunday. The Knights canceled last week's home game against Memphis.
UCF is hosting up to 1,000 National Guard members and 250 vehicles on its campus and using its stadium to stage recovery operations.
"We're honored to host the National Guard and play a part in helping our community and state recover from Irma," Central Florida athletic director Danny White said. "On behalf of our student-athletes, athletics staff and fans, I promise the Knights will do everything we can to assist in recovery efforts."
--Oklahoma quarterback Baker Mayfield apologized for celebrating the 31-16 victory over Ohio State by planting a Sooners flag at midfield at Ohio Stadium.
A year after hearing chants of "O-H, I-O" inside their own stadium, the Sooners got revenge on Saturday night as the Heisman Trophy hopeful threw for 386 yards and three second-half touchdowns.
Mayfield sprinted around the field waving a Sooners flag before stopping to emphatically plant it in the middle of the huge block "O" logo at the 50-yard line as his teammates cheered.
"I didn't mean for it to be disrespectful to any Ohio State people at all, especially the team or the players, because they're a great team and a great program," Mayfield told reporters Monday. "It was an emotional game. I knew that it was going to have a lot of implications on the playoffs. ... I got caught up in an emotional win. Yeah, it should've been something I did in the locker room. So I apologize for doing it in the middle of the field."
--No. 12 LSU is expecting to have All-SEC outside linebacker Arden Key back from injury for its conference opener at Mississippi State on Saturday, coach Ed Orgeron said.
Key, who set a school record with 12 sacks last season, underwent offseason shoulder surgery in early June. He was limited through camp and did not play in the Tigers' 2-0 start to the season.
"Arden Key has been cleared to play this week," Orgeron said. "He's going to work hard all week in full contact, and we're going to play him as much as we can. We'll see during the week how much he can do."
--The Southeastern Conference is discussing the effects of Hurricane Irma on the ability of No. 24 Florida to host No. 23 Tennessee on Saturday in Gainesville, Fla.
The game is scheduled for 3:30 p.m. ET.
"Now that the storm has passed through Gainesville, the University of Florida is working with local authorities to assess the effect of the storm on the campus and the Gainesville community, at the same time ensuring the appropriate security and local officials are available to host a game," SEC commissioner Greg Sankey said in a statement.
--The Baylor Bears are making a quarterback change after starting out 0-2, including a shocking upset loss to Liberty.
New coach Matt Rhule told reporters that sophomore Zach Smith will start Saturday at Duke.
Smith will replace Anu Solomon, who Rhule said was "banged up" in Saturday night's 17-10 loss to UT-San Antonio. It was UTSA's first-ever win over a Power Five team.
The Bears are 0-2 for the first time since 2003 and have lost eight consecutive regular-season games, including the 48-45 loss to FCS Liberty in the season opener.
--Rutgers offensive coordinator Jerry Kill suffered a minor seizure Sunday and remained hospitalized, head coach Chris Ash said.
"Coach Kill had a minor medical setback," Ash announced at his weekly press conference. "He is going to be fine. Saturday, early in the game after the first drive, he got tumbled up. He was really discombobulated in the first half from it and had some headaches Saturday night.
"It hasn't been confirmed or identified as the reason yet, but he had a minor seizure (Sunday) morning. But he is fine. He is still waiting to be released from the hospital. He will be back here this afternoon or tomorrow whenever he feels up to the task."
Ash said that Kill took a fall during Saturday's 16-13 loss to Eastern Michigan when a play reached the sideline and Rutgers quarterback Kyle Bolin took a late hit out of bounds.
