Charles Tuaau

College In 2011,

In February 2013, Tuaau signed with Oregon State University, although he failed to meet its academic requirements and ultimately transferred to Texas A&M University–Commerce instead. He also earned Lone Star Conference Defensive Player of the Year and Defensive Lineman of the Year honors and was named to the AFCA All-America first-team and Daktronics All-America second-team in 2013. He was selected as a Cliff Harris Award finalist as one of the nation's most outstanding defensive players at a "small college", and also helped lead A&M–Commerce to the 2014 Lone Star Conference championship.

Tuaau finished his two-year career at A&M–Commerce with 86 tackles, including 45 solo tackles, 34 tackles for loss, and 17 sacks. Because his May 2015 graduation ceremony fell on the same weekend that he was due to report to minicamp with the Chiefs, A&M–Commerce organized a special commencement ceremony for him. His wife, mother, and grandmother were all present as he became the first person in his family to earn a college degree. On August 24, 2015, the Chiefs experimented with moving him to the offensive line in practice, in what offensive coordinator Doug Pederson viewed as a learning experience for Tuaau. Pederson noted that Tuaau is "big, physical...powerful" and that he "fits that offensive line mode". However, he was cut by Kansas City on August 30, along with ten other players in the team's first round of cuts.

Miami Dolphins Tuaau signed a reserve/future contract with the Miami Dolphins on January 14, 2016.

IBM Big Blue In August 2017, Tuaau signed a contract to play for IBM Big Blue of the X-League in Japan.

St. Louis BattleHawks Tuaau signed with the St. Louis BattleHawks of the XFL during mini-camp in December 2019. He was waived during final roster cuts on January 22, 2020.
