Naufahu Anitoni Tahi (born October 30, 1981) is a former American football fullback. He was signed by the Cincinnati Bengals as an undrafted free agent in 2006. He played college football at BYU. Tahi has also been a member of the Minnesota Vikings and the Jacksonville Jaguars.
At Granger High School in West Valley City, Utah, Tahi was named the USA Today Player of the Year for Utah as a senior. Tahi rushed for a total of 5,700 yards and set a state record as the all-time leader in rushing yards and for rushing touchdowns.
Tahi attended Brigham Young University as a freshman in 1999 and led the team that year in rushing with 445 yards before taking a three-year leave for a mission in Jacksonville, Florida as he is a member of The Church of Jesus Christ of Latter-day Saints. Tahi returned to Brigham Young in 2003 and had a career-best 872 yards rushing from scrimmage as a senior and scored 8 touchdowns (6 rushing and 2 receiving).
Tahi signed with the Minnesota Vikings on November 22, 2006 to their active roster from Cincinnati's practice squad.
Tahi saw his first significant playing time in 2008. During that year, he was listed number one on the Vikings depth chart and played several games at fullback blocking for Adrian Peterson as well as playing on special teams. He also had 16 receptions for 37 yards, most of which came on one-yard dumpoffs in the flat, a favorite play of Brad Childress and the West Coast Offense playbook.
Tahi signed a $1.4 million offer sheet March 19 with the Cincinnati Bengals, but the Vikings matched the offer and re-signed him on March 27.
Tahi was raised in a family that are natives of Tonga, but he was born in California before moving to Utah as a child. Tahi is cousins with former BYU and former NFL fullback Fui Vakapuna. After retiring from football in 2012 Tahi became the running backs coach for Granger High School in West Valley City, Utah. Tahi graduated from Utah State University in 2016. He is now serving as a Graduate Assistant for the Utah State Aggies.
