CINCINNATI -- It was a busy weekend for NFL teams as the lead-up to free agency hit its fever pitch.

The 2015 free-agency period officially begins at 4 p.m. ET Tuesday. Still, some players in the last day or two have agreed to contracts with other teams that will be formalized just after the league year begins Tuesday afternoon. Others, like two Cincinnati Bengals, have re-signed with the teams that held their expiring contracts.

When it comes to the Bengals, you'll see even more personnel changes in the next couple of days. Free agents will be added from the outside, and other players who were under contract with Cincinnati in 2014 will sign elsewhere. To get you caught up on the moves the Bengals have already made this offseason, though, here's a quick look at where things stand as of Monday morning:
