Last season, Janikowski agreed to take a million-dollar pay cut and then dealt with a back issue which cost him the entire season.
In the Raiders' 2011 season opener at Denver, Janikowski tied what was then the record for the longest field goal in National Football League history: 63 yards, equaling a mark shared by Tom Dempsey and Jason Elam.

The soon-to-be 40-year-old is the Raiders' all-time leading scorer with 1,799 points, including 414 field goals. Gruden's first pick was Charles Woodson in 1998 followed by Mo Collins, Matt Stinchcomb in 1999, and Janikowski a year later. Giorgio Tavecchio, who the Raiders had kept on their radar since 2014, was the starting kicker in his absence and performed well.
Over the course of his career, Janikowski hit on 80.4 percent of his attempts and had a career long of 63 yards.
In 2016, Janikowski made 29-of-35 field goals (82.9 percent) and 37-of-39 extra points (94.9 percent).
