In a turnabout, the Broncos have tendered restricted free agent Tony Carter at the $1.542M right of first refusal* level. The low level tender gives Denver an opportunity to match an offer sheet signed by Carter with another team.
According to Aaron Wilson, "several teams" showed interest in signing Carter over the weekend, which presumably prompted the Broncos' decision. By tendering Carter at the lowest level, Denver retains the ability to sign Carter and trade him to an interested team.
* Carter was tendered at the ROFR level, not Original Round, as we'd first written.
