Source-derived summary

Jeffrey Richard "J. J." Jansen (born January 20, 1986) is an American professional football long snapper for the Carolina Panthers of the National Football League (NFL). He holds the record for the most games played by a Panther with 264 (43 more than the player with the second most, John Kasay) having held the record since Week 14 of 2022 against the Seahawks as his 222nd game. He played college football for the Notre Dame Fighting Irish and was signed by the Green Bay Packers as an undrafted free agent in 2008, but never appeared for the team. As of the 2025 season, Jansen is the longest-tenured player on any team in the league.

Early life

Jansen attended high school at Brophy College Preparatory in Phoenix, Arizona. He attended Rancho Solano Private School prior to that, where he starred as quarterback, leading the RSPS Mustangs to an MVAL championship in 1999.

Professional career

Green Bay Packers

After going unselected in the 2008 NFL draft, Jansen signed with the Green Bay Packers. He appeared in four preseason games for the Packers, and on August 30, 2008, he was waived/injured. Jansen reverted to injured reserve the next day and spent the entire 2008 season there.

Carolina Panthers

The Packers traded Jansen to the Carolina Panthers for a conditional pick in the 2011 NFL draft on April 13, 2009.

Editorial summary

The public source identifies “J. J. Jansen” as player of American football. This brief keeps that definition visible, then builds a research path around Jansen, player and American.

Editorial reviewA useful biographical orientation record, particularly for establishing names, roles and a first chronology. The current lead gives the account dated anchors—1986, 2022, 2008, 2025—that can be checked directly. The linked authority record independently contributes the date 1986-01-20. Its value is orientation rather than verdict, with Jansen, player and American providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “J. J. Jansen”, the useful work is to connect “player of American football” to the records capable of establishing context and consequence.

Evidence profile

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q3156805. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1986, 2022, 2008 and 2025.

Critical limits

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
