Senior Day had a little extra meaning for the South Carolina State football team Saturday afternoon.

With 4:34 remaining in the opening quarter against Savannah State, the Bulldogs sent out 55-year-old senior running back Joe Thomas Sr. onto the field for the first time. Thomas then took the handoff and gained three yards in his collegiate debut.

There's no official way of confirming if Thomas is the oldest player to ever appear in a college football game, but many believe it to be true. Thomas enrolled at the university at 51 years old along with his son Joe Thomas Jr. — now a Green Bay Packer — and practiced on and off with the team as a scout player over his four years.

Thomas was then cleared by the NCAA to play two weeks ago and the Bulldogs officially added him to their roster Saturday morning.

Even if Thomas doesn't see another snap Saturday, he's accomplished quite a lot. To read more about Thomas' story, check out Sports Illustrated's feature on him earlier this week.
