Key Points:

• Virginia Tech recorded back-to-back strip sacks against Old Dominion, with Tyson Flowers recovering a fumble for a defensive touchdown after an earlier fumble by Keon Wylie prevented a score.
• The No. 6 Oregon vs. Oklahoma State game kickoff is delayed due to lightning strikes near Stillwater, with NCAA policy requiring a 30-minute lightning-free period within 8 miles before play can resume.
• Several college teams are showcasing special uniforms today, including Georgia's all-white set, Tulane's Mardi Gras-themed gear, UTEP's all-black "Heritage Night" uniforms, and Boise State's hand-printed helmets featuring the old Broncos logo.
• Akron quarterback Marty Whims II will lead the offense for the first series against Robert Morris as part of a promotional event, receiving strategic advice from Nick Saban on play-calling and game management.
• Key matchups to watch include No. 1 Ohio State vs. No. 4 Texas and No. 11 Oklahoma at Michigan, where Michigan's quarterback Bryce Underwood faces pressure after a narrow win and the team’s recent drop from the AP Top 25 poll.
• The Memphis vs. Boise State game could be pivotal for the Group of Six playoff race, with Memphis coming off a win and Boise State seeking redemption after a close loss to Oregon; the winner may gain an early playoff advantage.
