Brian Robison figures it’s time to think about retirement.

The Vikings defensive end agreed to rework his contract last month, giving him two years remaining. He said Friday that 2018 likely will mark his final NFL season.

“I really do believe that probably at the end of those two years, it will be it,’’ Robison told the Pioneer Press. “It’ll be about my time to call it (a career), but we’ll see how I feel when I get there. … But I would say that more than likely, that will probably be the time that I’m going to have to lay things to the side and get ready for life after football.’’

Robison, who turns 34 on April 27, has played 10 seasons, all with Minnesota. Two more will make it a dozen.

“This solidifies me to be able to retire as a Minnesota Viking,’’ Robison said of his restructured contract.

Robison originally had one year left on his deal, a nonguaranteed $5.6 million for 2017. He agreed to drop his base salary to a guaranteed $3.9 million while also getting a $100,000 workout bonus. In exchange, Robison got 2018 tacked onto his deal for a base salary of $3.2 million, with $1.25 million guaranteed, and with a $200,000 roster bonus and $100,000 workout bonus.

Yannick Ngakoue’s listless Vikings debut left ‘a bad taste in my mouth’ The move created an additional $1.8 million in 2017 salary-cap room for the Vikings. Robison had been expecting the Vikings would want to renegotiate, and he got a call early last month from his agent, Vann McElroy, saying the process was underway.

“It was an opportunity for both sides to get what they wanted,’’ said Robison, who will at Winter Park on Monday for the start of offseason workouts. “Something you don’t necessarily see in this league anymore is loyalty on both sides. … I had a long talk with (general manager) Rick Spielman, We were on the phone for probably 45 minutes, just discussing it.

“I understood what was going on, but at the same time they wanted me to know there was nothing I did wrong or anything like that. They just felt it was an opportunity that could work out for both sides, and I 100 percent agreed with them.’’

Robison said negotiations went “smoothly” and took about two weeks. Details of the new deal surfaced March 24.

“It’s never been about the money, it’s about making sure I give (the Vikings) the best chance to win and bring a championship to Minnesota,’’ Robison said.

Robison has begun to think plenty about life after football. An avid fisherman, he said he likely will do something in that industry, perhaps being a television commentator for tournament coverage.

Until then, Robison, drafted in 2007, will be the longest-tenured player on the Vikings. Linebacker Chad Greenway, who arrived in 2006, retired after last season and running back Adrian Peterson, also drafted in 2007, is a free agent who won’t be re-signed.

“It feels a little weird, but at the same time I thought it would happen,’’ Robison said of the departures by Greenway and Peterson. “You usually don’t get to play in this league this long, much less with the same team, and it’s something I’m definitely proud of.’’

Robison was one of Minnesota’s four captains for the first time last season, a role he figures to retain. Regardless, he said he would not complain if third-year man Danielle Hunter takes over his starting job in 2017.

“We’re going to compete,’’ Robison said. “But if he’s able to beat me out, then hats off to him. I’m not going to be one of those guys that gets upset if they get beat out.’’

Whatever his role, Robison is determined to make up for last year, when Minnesota lost eight of its final 11 games after a 5-0 start. Additional motivation is the Vikings seeking to become the first team to play a Super Bowl in their home stadium.

“It’s very exciting,’’ Robison said. “It’s an opportunity for us to do something nobody has ever done before.’’

Robison is undeterred that the Vikings won’t be bringing back a number of players. Offensive linemen Brandon Fusco and Mike Harris were released in February, and of 17 unrestricted and restricted free agents, only wide receiver Adam Thielen and cornerback Terence Newman have been re-signed.

“I’ve been around this league long enough where nothing really surprises you anymore,’’ Robison said. “I just think sometimes there are better opportunities for some people and for some people there aren’t. For me, I wanted to be here in Minnesota. I believe in this team, I believe in this coaching staff. I believe in this organization, that we can get the job done. … At the end of the day, you can’t really concentrate on those guys (that left). You got to move forward.’’

Minnesota’s offseason workouts will include organized team activities on May 23-25, May 30-June 1 and June 5-8, and a June 13-15 mandatory minicamp. During a break, Robison’s Reel ‘Em In Foundation will hold a charity fishing tournament May 12-14 at Wabasha.

It’s the first such event in Minnesota for the foundation, launched in 2015, and proceeds will benefit K9s4COPs. Current and former Vikings expected to participate include Hunter, Greenway, Everson Griffen, Chuck Foreman and Carl Lee.

“We’re hoping to raise a bunch of money,’’ Robison said.
