EDGE Analysis

Nelson had his surgery done by Dr. James Andrews, who reportedly did not need to fully repair the meniscus. This is good news for the former Wisconsin cornerback, who was ticketed for a Day 3 selection in the upcoming NFL Draft prior to the injury. Nelson's recovery is expected to take six weeks, so he should be ready for training camp.

Nelson suffered a torn meniscus during a private workout and is expected to be out for 3-to-4 months, Ian Rapoport of NFL Network reports.

EDGE Analysis

The Wisconsin product is due to have surgery next week to repair the injury. The lengthy recovery time leaves Nelson's status for the start of training camp in question but he is expected to be a full-go for the start of the season. Whether this injury causes a slide remains to be seen, but Nelson was already likely ticketed for a Day 3 selection before this news.

Titans hired free agent DL Nick Eason as assistant defensive line coach. Eason, 34 in May, was out of the league this past season after appearing in all 16 games and making nine tackles in 2012 with the Cardinals. The former fourth-round pick of the Broncos registered 128 tackles and seven sacks as a reserve across ten seasons with the Broncos, Browns, Steelers, and Cardinals.

Cardinals DL Nick Eason has dropped 40 pounds to 282 after taking up boxing and changing his diet this offseason. "I realized that I could probably help myself and extend my career if I lost a little weight," Eason said. The difference is huge. I feel a lot quicker now. I have a lot more endurance." The 32-year-old graded out poorly as a run defender in 2011, according to Pro Football Focus.

Cardinals agreed to terms with DE Nick Eason on a two-year contract. The 31-year-old Eason has ties to new Cardinals defensive coordinator Ray Horton from their time together in Pittsburgh. Beat writer Kent Somers confirms that this signing was made strictly for depth. Eason knows the zone-blitz schemes Horton learned from Dick LeBeau, but he wouldn't be effective in a big role.
