Valentin Senn

Senn was born 23 April 2001 in Volders, Austria. He mainly played soccer as a child and did not begin to play American football until 2015, instead playing trumpet for the Swarovski Orchestra and singing in the Stimmpfeffer choir. When he first played football, Senn played wide receiver, and then tight end. He switched to offensive tackle when he was on his way to college.

Senn was the number-two prospect in Europe and the number-one prospect in Austria. He was recruited by the University of Colorado Boulder and spent two years there. Senn spent his first year as a redshirt before starting his redshirt-freshman year. He transferred to University of Connecticut (UConn), where he played for three years. Senn played 41 games at UConn, including 38 straight starts at left tackle. Senn started all 13 games for UConn in his sophomore year, and all 12 in his senior year, following which he was named to the East-West Shrine Bowl 1000 watchlist.

Senn changed his number from 71 to 69 and then signed as an undrafted free agent with the Arizona Cardinals. Senn was the 17th player on the practice squad under the international exemption rule (also known as the international gateway program). He suffered a neck injury before the 2025 NFL season and missed the entirety of it. He was drafted 9th overall in the Canadian Football League international draft by the Toronto Argonauts but did not sign with the team.

On August 30, 2026, Senn was waived by the Cardinals and re-signed to the practice squad.
