The Bengals on Tuesday extended a tender offer to center T.J. Johnson, whose contract is set to expire Thursday.

The tender to Johnson, a fourth-year NFL player, makes him a restricted free agent. The 6-foot-4, 300-pounder can negotiate with other teams, but the Bengals can match any offer. If Johnson does not sign with another team, he can sign a one-year tender with the Bengals or a long-term deal.
