The 2025 college football season kicks off Week 4 with four live games on CBS Sports Network, offering a Saturday packed with high-stakes action. The day begins with high-scoring North Texas looking to push the pace against Army in a key American Conference battle.

Action continues in the afternoon as Ball State visits UConn, with both teams chasing their first FBS win of the season. The Huskies have dropped back-to-back games in overtime and will look to turn the tide at home.

California true freshman quarterback Jaron-Keawe Sagapolutele has not missed a step since winning the job in Berkeley to open the season, quickly emerging as a rising star both in the ACC and nationally. The former top-50 recruit in the 2025 class has powered the Golden Bears to a 3-0 start, putting them one win away from their best opening stretch since 2019 when they visit San Diego State (1-1) on Saturday night. The Aztecs and second-year coach Sean Lewis are just 1-5 at home against FBS opponents since the start of last season.
