Floyd lined up next to NT Letroy Guion, in place of three-technique Kevin Williams. Floyd isn't expected to take overtake Williams in year one, but he's certainly viewed by the organization as the future at the position. He'll still see plenty of snaps this season as a rotational lineman.

Carlson signed a five-year, $25 million contract last offseason. He sustained a knee injury in camp and never got going, catching eight balls in 14 games. Now he's accepted a pay cut and is healthy. Carlson will enter camp as the clear No. 2 tight end behind Kyle Rudolph.

Greenway had some "residual fraying" of his meniscus. It may have been related to his 2006 ACL tear in the same knee. Regardless, he's in no danger of missing Week 1 and fully expects to be ready for the start of camp. "There will be no doubt in my mind unless I get in a car accident or something," said Greenway. "From the knee perspective, it'll be 100 percent, good to go."

"There are enough people around the league that believe Matt Cassel is good enough to challenge Ponder," stated Schefter, adding that Cassel "could unseat Ponder at some point this season." Although Schefter confirmed Ponder won't lose his job before Week 1, he called it a "situation that bears watching." Ponder endured a brutal nine-game stretch last season (Weeks 7-16) where he completed 140-of-245 passes (57.1 percent) for just 1,267 yards (5.17 YPA), and a 7:8 TD-to-INT ratio with two lost fumbles. Ponder was serviceable to solid (67.2 percent, 7.01 YPA, 11:4) in his other seven starts.

Childs is listed at 217 on the team's official website, but what makes it so much more impressive is that he had dipped all the way to 180 last winter. Childs was recovering from double patellar tendon tears, and the pain medicine made him sick to his stomach. He's now lifting "crazy weight, like lineman weight" as his recovery is ongoing. Childs could be medically cleared for the start of training camp, but any contributions in 2013 would be a surprise.

Childs has been sprinting and cutting since last month and caught passes in front of reporters following Tuesday's OTA practice. Just 10 months removed from his second major knee surgery, the Vikings will continue to exercise caution, but an early-August return hasn't been ruled out. "I'm waiting on our medical staff to give us the green light," coach Leslie Frazier said. "We'll see what happens. I'm not sure what direction it will go."

Allen missed the start of OTAs due to a family obligation, and still isn't 100 percent after surgery to repair a torn labrum. He remains on track to be healthy for training camp. Allen will attend the minicamp, but not practice.
