The Cleveland Browns are officially on the board, signing former Los Angeles Chargers guard Zion Johnson to a three-year deal.

The Browns are signing Zion Johnson to a three-year, $49.5 million contract.

Baltimore, Philadelphia and Pittsburgh each were awarded a league-high four compensatory picks in next month's NFL draft based on their losses and signings in last year's free agency.

The Pittsburgh Steelers will have added ammunition when the draft comes to town next month.

According to the report, it is a two-year deal worth $14 million.
