If you follow football, you've heard it before: "NFL" stands for Not For Long.
It's a fickle league, one that is high on youth and potential and one that demands much of its players -- so much, in fact, that the average career spans 3.3 years (according to the NFL Players Association).
So when a player remains in the league for 18 seasons -- as is the case for Raiders safety Charles Woodson -- it's impressive. When he is still a playmaker at 39 years old, it's downright remarkable.
Woodson leads the league with four interceptions (tied with Mike Adams and Josh Norman) and has notched 26 tackles through five games this season, as the Raiders had their bye in Week Six. He's tied for sixth all-time on the career interceptions list, with 64. He needs only two more to move into the top five and pass Ken Riley, who currently sits fifth with 65 interceptions.
"[Woodson] is one of the greatest players in the NFL, at any position, of all time," offensive coordinator Frank Reich said. "We all know he's going to be a first-ballot Hall of Famer. You love going against guys like that."
Sunday, Chargers quarterback Philip Rivers will face Woodson. To hear what Rivers had to say about the eight-time Pro Bowler and Super Bowl Champion, watch the video above.
Injury report: OL DJ Fluker, RB Melvin Gordon, OL Chris Hairston, WR Stevie Johnson and C Chris Watt were limited Thursday. LB Manti Te'o, WR Keenan Allen, TE Antonio Gates, CB Craig Mager, LB Tourek Williams and S Eric Weddle did not pratice.
Though Watt, Hairston and Fluker were limited, Thursday's practice was significant, as it marked the first practice in which all five starting offensive linemen were on the field together in weeks. LG Orlando Franklin and LT King Dunlap participated in full.
