Despite the many moves the Detroit Lions have made this offseason, they have just over $4.5 million of salary cap space, according to Jason La Canfora, of the NFL Network.

Three weeks ago, at the start of free agency, the team was right up against the salary cap. Thanks to Calvin Johnson's new contract, however, the Lions were able to give themselves room to maneuver.

Since then, Detroit has spent the, ahem, Lion's share of the free-agency period on re-signing its own key players, like linebacker Stephen Tulloch, left tackle Jeff Backus and running back Kevin Smith, among others.

The Lions carried over $1.36 million of cap space from the 2011 season. Combined with $2.8 million of adjustments, the team's adjusted cap increased to $124,766,555. Right now, 47 contracts take up $120,246,822.

In terms of available cap space, Detroit is second only to Minnesota ($14,574,450) among the NFC North teams. Chicago ($3,540,835.00) and Green Bay ($3,425,983.00) are third and fourth in the division.
