Sunday marked the end of an era for Oakland Raiders fans. With the team planning to move to Las Vegas for next season, Sunday's matchup against the Jacksonville Jaguars was the last home game for the team at RingCentral Coliseum.

Raiders fans are well known for being some of the most passionate fans in the NFL but on Sunday, one fan took the term passion to the next level.

The unidentified fan appears to have somehow taken a seat from the stadium, collecting a unique piece of memorabilia in the process.

The Raiders originally moved into the Coliseum in 1966 when it was known as the Oakland-Alameda County Coliseum. After a 12-year stint in Los Angeles from 1982-94, the Raiders moved back into their original venue which also hosts the Oakland Athletics Major League Baseball team.

After being up 16-3 at half time the Raiders would fall 20-16 after allowing Jaguars quarterback Gardner Minshew to throw two touchdowns in the last 5:15 of the game. With the loss, the Raiders fell to 6-8 on the season after starting a promising 6-4.

And while Oakland isn't technically eliminated from playoff contention this year, the late-season slide has been disappointing for fans to say the least.

The team's new stadium in Paradise, Nevada is expected to be completed in the summer of 2020. The 72,000-capacity dome will also serve as the home field for the UNLV college football team. Allegiant Stadium reportedly cost about $2 billion to build.

While Raiders fans in Oakland will certainly miss the old coliseum, at least one fan has a lasting relic of the stadium.
