Vikings running back Adrian Peterson was in New York to meet with the NFL on Tuesday regarding his potential reinstatement. The meeting lasted more than three hours before Peterson exited the league's offices. The NFL made no official ruling regarding his status after the meeting.

Peterson remains eligible for reinstatement from the commissioner's exempt list April 15. NFL Commissioner Roger Goodell wanted to check in with Peterson before then, so he was summoned to New York to meet with Goodell, NFL senior vice president of labor policy Adolpho Birch and others from the league office.

One of the terms Goodell originally set for Peterson's reinstatement was that he needed to meet with a league-assigned psychiatrist to design a counseling and therapy program. Whether Peterson has met Goodell's requirements is believed to be one of the things discussed during the meeting.

Peterson was suspended by the NFL in November after he pleaded no contest in the child-abuse case involving his young son and was told he would be eligible for reinstatement April 15. But the league moved Peterson from the suspended list back to the exempt list in February after a federal judge ruled to void a league-appointed arbitrator's decision to uphold the suspension.

The league has not revealed a timeline for a decision, but if Peterson is reinstated in the coming days, he can officially return to the Vikings for the first time since September.

However, it is unclear if Peterson intends to report if reinstated. His agent, Ben Dogra, recently said the disgruntled running back would be better off playing elsewhere going forward.

The Vikings, meanwhile, expect Peterson to be their starting running back this season. Peterson is under contract through the 2017 season and will make a base salary of $12.75 million in 2015.

The team's offseason workout program begins on April 20, but the majority of it is voluntary. June's mandatory minicamp would be the first time he is contractually obligated to report to Winter Park.

Sullivan gets new deal

The Vikings and center John Sullivan finalized a one-year contract extension that will keep him under team control through the 2017 season. Sullivan also received raises in base salary as part of the deal.

Sullivan has a new base salary of $5.9 million this season. He has a base salary of $5.4 million in each of the 2016 and 2017 seasons. He had been scheduled to make a base salary of $4.65 million both this season and next.

While the offensive line did not perform up to expectations in 2014, Sullivan continued to be a consistent performer in the middle. He started all 16 games for a third consecutive season and has started 93 games since joining the Vikings in 2008.

"I want to start by saying thank you to the Minnesota Vikings for putting their faith in me as a person and football player," Sullivan said in a news release. "The Vikings have been with me through professional highs and lows, and have stood by my side and supported me through personal hardships. My ability to express the true depth of my gratitude comes from my actions on and off the field.

"I intend on doing absolutely everything I can to ensure we attain our ultimate goal of a Super Bowl championship on the field, and that I live my life in a way that is commensurate with that standard off the field."

Prospects fly into town

With the NFL draft a little more than three weeks away, the Vikings are finishing their fact-finding on this class of prospects. That process includes having several of the top prospects in for a visit this week.

According to ESPN, the Vikings invited potential first-round picks such as Nebraska defensive end Randy Gregory, Michigan State cornerback Trae Waynes and Gophers tight end Maxx Williams, among others, to the Twin Cities for visits that will continue into Wednesday.

NFL teams are permitted to conduct 30 player visits at their facilities each year.
