Weaver began his collegiate career at Modesto Junior College, playing for the Pirates from 2022 to 2024. He was named the team's starting quarterback as a freshman but suffered a dislocated hip in the third game, causing him to miss the remainder of the season.[2] After recovering, he returned as the full-time starter for the next two seasons.[3] During his time at Modesto, Weaver threw for 5,823 yards and 48 touchdowns.[4] He led the Pirates to back-to-back conference championships and earned several honors, including being named a 3C2A All-American in 2024.[3] Weaver was also a two-time 3C2A All-State selection and a two-time Valley Conference Offensive MVP.[5]
In 2025, Weaver transferred to the Hawaii Rainbow Warriors, where he served as the primary backup to Micah Alejado. He made his Rainbow Warriors debut in the season opener against Stanford, attempting one pass. The following week against Arizona, Alejado suffered a sprained ankle and Weaver entered the game, completing 8 of 16 passes for 66 yards with two interceptions in a 40–6 loss.[6] Weaver made his first FBS start the following week against Sam Houston, completing 27 of 43 passes for 294 yards with three touchdowns and one interception in a 37–20 victory.[7] The following week, he started against Portland State, completing 26 of 42 passes for 240 yards and two touchdowns in a 23–3 win.[8]
Weaver later appeared in the 2025 Hawaii Bowl against California, where he came off the bench in relief and threw the game-winning 22-yard touchdown pass with 10 seconds remaining as Hawaii rallied from a 21–0 deficit to win.[9][10] Overall, Weaver appeared in five games during the 2025 season, completing 63 of 105 passes for 628 yards and six touchdowns while rushing for 73 yards. Following the season, Weaver entered the NCAA transfer portal.
Weaver transferred to San Jose State on January 9, 2026.[11]
