Charles Woodson wants to play another NFL season, and he’d like to do so in Oakland. The Raiders have made it clear they want him back.

That doesn’t mean the veteran safety will play for free. Woodson said Thursday that he’d consider retirement if he doesn’t get a fair offer from the silver and black.

“If the right numbers don’t come across for myself and from the team standpoint, it’s a serious consideration, at this point, that I could’ve played my last season in the NFL,” Woodson said in an interview with Sirius XM radio. “That’s something that I think about. I do plan on playing another year. Hopefully something can get done with the Raiders and, if not, I would have to take a hard look at last year being the last one.”

Could there be trouble at the negotiating table?

According to NFLPA documents, Woodson played the 2013 season under an incentive-laden deal ultimately worth $3.3 million. He had a $1.7 million base salary, a $100,000 workout bonus and more money to be earned based on playing time. Woodson played 99.3 percent of the Raiders defensive snaps, which tacked on another $1.5 million for exceeding 90-percent snap threshold.

Woodson’s exact demands are unknown. The 37-year old played well at times and below average at others. He was forced to play as a single-high free safety on most snaps after strong safety Tyvon Branch went down in Week 2, removing his ability to make plays closer to the line of scrimmage.

Woodson was second on the team with 133 tackles. He also had two sacks, interception, eight passes defensed, four forced fumbles and two fumble recoveries. He returned one for a touchdown.

Not bad for an old man. Woodson expressed concern that his age weighs heavier in contract talks than his recent play.

“When you get past a certain age, it’s no longer about what you do on the field,” Woodson said. “It’s about your age. They look at the age first and then what you do on the field second. There’s no rush for any team to sign a veteran player. It’s not just a Raiders situation. It’s a league-wide deal.”

Woodson didn’t plan on returning to the Raiders last year. The team’s No. 4 overall pick in 1998 planned on joining a Super Bowl contender, either in Denver or San Francisco. He was wooed back by fan support and financial incentives, and enjoyed his second stint in Oakland.
