The Minnesota Vikings' problems at wide receiver got worse on Wednesday, as Percy Harvin's migraine headaches returned and attempts to land disgruntled Chargers wideout Vincent Jackson failed.
The Vikings were willing to give up a second-round choice and an additional conditional pick to the Chargers and had worked out a financial deal with Jackson, a source told ESPN.com's John Clayton. But a 4 p.m. ET deadline came and went without a trade taking place.
Neil Schwartz, one of Jackson's agents, told The Associated Press he had worked out a one-year deal with an option with an average salary of more than $9 million. He declined to name which team had offered the deal.
Harvin missed Wednesday's practice because of migraine headaches, not the hip injury that has been plaguing him for the past week, the Vikings announced.
Harvin recently said he thought his migraine problems had been solved when it was determine sleep apnea was the cause. For the past couple of weeks, Harvin has been spared from the debilitating headaches that caused him to miss a significant chunk of training camp.
But on Wednesday, the migraines returned and Harvin didn't practice.
So the Vikings, with an 0-2 record and a total of 19 points scored in two games, did two things: They signed Hank Baskett and, according to sources, reached out to the Chargers about acquiring Jackson.
Jackson and his potential suitors were facing a 4 p.m. ET deadline for him to be eligible to play in Week 5, under a deal worked out by the NFL and the players' union. Otherwise, Jackson, who has not played a down this season in a contract squabble with the Chargers, would have to sit out the first six weeks of the season -- three games for an NFL-mandated suspension and three more as a result of the Chargers placing him on the exempt list.
The deal didn't happen -- and Jonathan Feinsod, one of Jackson's agents, squarely blamed the Chargers and general manager A.J. Smith.
"We had multiple offers and the Chargers squashed them all," he said.
"Archie Manning had it right," Fiensod said, referring to the elder Manning not wanting his son, New York Giants quarterback Eli Manning, to play for the Chargers, the team that drafted him in 2004. "They call [Smith] the Lord of No Rings for a reason."
The Chargers declined comment on Jackson on Wednesday.
