There were several tributes during Saturday's slate of college football games to honor late members of the sports community.
Before a dominating performance against Florida State, Louisville honored the late Muhammad Ali. Ali, nicknamed The Greatest, passed away this summer.
The Cardinals honored their hometown hero by putting butterfly decals that read "Ali" on the back of their helmets. The same butterfly was painted behind one of the end zones. It was a reference to Ali's most famous quote: "Float like a butterfly, sting like a bee."

Just before the Cardinals ran out of the tunnel, a video with clips of Ali played, energizing the crowd. In the video, Ali stated how much being from Louisville meant to him.

The University of Tennessee recently lost one of its greatest, Pat Summitt. Summitt, the most winningest college basketball coach in history, passed away in June after a battle with Alzheimer's.
The Vol's marching band spelled out "Pat" during the halftime show.
Perhaps the most touching tribute of the day was one that was done quietly before Oregon's game against Nebraska.
The Oregon Ducks, like many, honored Nebraska's late punter Sam Foltz. Foltz was killed in an automobile accident in July when traveling home from a football camp with Michigan State punter Mike Sadler and LSU punter Colby Delahoussaye. Sadler was also killed, and Delahoussaye survived.
Oregon's head coach Mark Helfrich and kicker Matt Wogan placed a green and yellow bouquet of flowers on the 27-yard-line to memorialize Foltz, who was No. 27.
I was told that Helfrich and his kicker laid the flowers when the stadium was almost completely empty. A deep gesture. And typical Helfrich.— Paul Myerberg (@PaulMyerberg) September 17, 2016
Finally, Penn State held a controversial tribute before its game.
The Nittany Lions honored former head coach Joe Paterno Saturday, the 50th anniversary of his coaching debut. Paterno, who died in 2012, was involved in the school's horrific scandal involving Jerry Sandusky.
Fans cheered as the team played videos honoring Paterno's career and family, but some of the Temple fans in attendance were seen turning their backs.
