Calvin Johnson will grace the cover of "Madden NFL 13" after winning a contest driven by fan voting. The Lions wide receiver beat out Panthers quarterback Cam Newton for the honor. Johnson, who won by garnering 52 percent of the more than 651,000 votes cast in the competition, said he was "shocked" by the decision. "Man, it's great," he said. "Just to see yourself on this Madden (cover) and seeing all the guys that have been on Madden? C'mon, man."

Lions running back Jahvid Best has not been limited during the team's voluntary offseason program. Jim Schwartz said Saturday that Best is "doing the same things everybody else is doing." Best is coming back from a season-ending concussion. "I saw (Best) in the meeting room, but I haven't seen him working out," Martin Mayhew said of Best, who 11 games last season because of a concussion sustained against the 49ers. "From what I understand, he's been doing everything, as far as conditioning and working out with everybody."

This year's bracket-style tournament to select a cover athlete for the 2013 version of the wildly popular Madden video game is down to Calvin Johnson and Cam Newton. Voting runs through next Wednesday.

Nate Burleson is well aware of the Madden curse, but that doesn't mean he doesn't want to see Calvin Johnson on this year's cover. Burleson plans to vote for Johnson during the semifinal round of the Madden 2013 Cover Vote. Johnson faces Aaron Rodgers in the semis, while Cam Newton is squaring off against Patrick Willis. "Of course, I would love to see my guy on the cover of Madden," Burleson said. "I'm a big Madden fan. I do believe in the curse, but there's certain curses that can be erased with dollar signs, so we'll see what happens. I'm just keeping it real."

In a television interview with WXYZ in Detroit, Lions president Tom Lewand provided some insight into the team's thinking this offseason. "We're so excited about what we accomplished last year. We know we've got a lot of work to do this year, but we've got a great nucleus of young players in Matthew Stafford, Calvin Johnson, Ndamukong Suh and Louis Delmas and so many other guys that really have a focus about getting back to work. They all come back on April 16, just next week, to get ready to roll," he said. "I think it was summed up best by Calvin when we signed him to that big extension. The first thing he said in the press conference was, 'I just want to get back to work.' And we all do. It's exciting to get those young guys, those young talented guys back to work winning football games." When asked about the team's chances in 2012, Lewand set the bar pretty high going forward. "Our focus is on getting better. Last year wasn't good enough for us. Our goal is not to be a wild card participant. Our goal are a lot higher than that. People say to us all the time, 'What a great year, what a great year.' "Well, you know what -- it wasn't a great year. It was okay. It was a step in the right direction, but we've got a lot of work ahead of us and our goals are out there to be achieved and that goal ultimately is Super Bowl championships, not just one, but many."

Cliff Avril will participate in Detroit's first offseason workouts, which start next Monday, if he receives a long-term deal from the team. Negotiations are currently at a standstill. "I think we're going to continue to try and get something done hopefully and we'll see how it goes," said the defensive end. Avril doesn't have immediate plans to sign his one-year franchise-tag tender of $10.6 million and is hoping to work out a long-term extension before the contract deadline of July 15.
