Jerick McKinnon RB MIN 8 Days

McKinnon is fully recovered from the back injury that landed him on IR to finish the 2014 season, the St. Paul Pioneer Press reports.

Per the report, McKinnon, who the Vikings list at 5-9 and 208 pounds, is currently working to add upper-body strength and endurance, with an eye toward helping him better withstand the rigors of the NFL and to aid him as a pass protector. In any case, McKinnon's role (and fantasy upside) this coming season continues to largely hinge on Adrian Peterson's future with the team.

Alan Ball DB JAC 8 Days

The Panthers have signed Ball to a one-year deal, reports.

Ball, who recorded 22 tackles and a pick in seven starts for the Jaguars in 2014 prior to landing on IR with a biceps injury, is thus a candidate to start at cornerback for the Panthers this coming season opposite Josh Norman.

Charles Clay TE BUF 8 Days4 Comments

The Dolphins will not match the five-year, $38 million offer sheet that Clay signed with the Bills, ESPN's Adam Schefter reports.

While the Dolphins are content to proceed with a tight end corps headed by Jordan Cameron and Dion Sims, Clay now tops the Bills' depth chart at the position, on the heels of a 2014 season in which he caught 58 passes for 605 yards and three TDs in 14 games for Miami. Clay battled through knee and hamstring issues this past season, but assuming his health, he'll be a big part of the Bills' offense in 2015, with a decent boost in his numbers a reasonable expectation. The Bills are clearly banking on such an outcome, having made Clay the fourth-highest paid tight end in the NFL, per the Buffalo News.

Mitch Unrein DL SD 9 Days

Unrein signed a two-year deal with the Chargers on Wednesday, ESPN's Adam Schefter reports.

Unrein spent the last four seasons with the Broncos, but was limited to one tackle over eight games in his 2014 campaign. He'll look to compete with the likes of Sean Lissemore and Ryan Carrethers for reps at defensive tackle in San Diego's 3-4 defensive scheme.

Daniel Fells TE NYG 9 Days

Fells has signed a one-year deal to return to the Giants, the Daily News reports.

Fells, who caught 16 passes for 188 yards and four TDs this past season, brings valuable experience and blocking skills to the table for the Giants, whose TE corps also includes Larry Donnell and Adrien Robinson. That said, Fells' limited targets cap his fantasy upside, despite his occasional trips to the end zone.

Kroy Biermann LB ATL 9 Days2 Comments

The Falcons have re-signed Biermann, reports.

Biermann, who notched 75 tackles and 4.5 sacks for the Falcons this past season, returns to further bolster an Atlanta defensive line that has also added Adrian Clayborn and O'Brien Schofield to the mix this offseason.

Greg Hardy DL DAL 9 Days8 Comments

Hardy has signed a one-year deal with the Cowboys, reports.

Per the report, Hardy's incentive-laden contract with the Cowboys could be worth up to $13.1 million. Hardy, who remains on the Commissioner's Exempt List, could face a suspension to start the upcoming NFL season, but when the defensive end (who recorded 15 sacks for the Panthers in 2013) takes the field for Dallas, he'll provide his new team's pass-rush with a major boost.

Bernard Pierce RB JAC 9 Days5 Comments

The Ravens have released Pierce, the Baltimore Sun reports.

The move follows the running back's arrest early Wednesday morning on DUI charges. The departure of Pierce, who carried 93 times for 366 yards and two touchdowns in 13 games for the Ravens this past season, leaves the team with a running back depth chart currently headed by starter Justin Forsett and second-year pro Lorenzo Taliaferro.

Percy Harvin WR BUF 9 Days4 Comments

Harvin's deal is now official, reports.

We're certain his relationship with coach Rex Ryan helped speed this along, in what's believed to be a one-year deal. As for his role with the Bills, it'll be interesting to see whether the Bills use Harvin's speed in an all-purpose type role, or if he can edge out Robert Woods and earn a more traditional No. 2 receiving spot behind Sammy Watkins. One thing's for sure in that Harvin adds a much-needed speed element to a decent receiving group but one that pre-Harvin featured more hands and strength amid the group of Watkins, Woods, and Chris Hogan. If Charles Clay ends up signing with the Bills and Matt Cassel ends up beating out EJ Manuel, it's possible the team could enter the season with a new quarterback, running back, key wide receiver, tight end, and fullback.

Nick Toon WR NO 9 Days

With Kenny Stills being traded to the Dolphins, Toon now sits third on the Saints' wide receiver depth chart. Toon finished the 2015 season with 17 receptions for 215 yards and a touchdown - all of which came over the final six games of the season.

While he's currently third on the depth chart, the Saints often deploy three-receiver sets, with Brandin Cooks most likely to operate as the slot receiver. Slated to play opposite a possession-minded receiver in Marques Colston, Toon isn't the prototypical deep threat the Saints have consistently played in that role in years past. Yet, both Toon and Colston managed to co-exist just fine the second half of the season, with Toon flashing enough skills to plant him on the fantasy radar in 2015 in deeper leagues, if he's able to hold onto his spot on the depth chart.
