The Kansas City Chiefs and Baltimore Ravens used the unrestricted free-agent tender on pass-rushers Melvin Ingram III and Justin Houston, respectively, on Monday.

The UFA tender is rarely used. It was last used by the New York Giants in 2020. If either player signs with a new team before July 22 or the first day of training camp, whichever is later, the signings would count toward the NFL's compensatory formula.

If they don't sign by the deadline, the teams would retain exclusive negotiating rights to the respective players at 110% of their 2021 salaries, according to the NFL's Collective Bargaining Agreement.

For Ingram, that would be $4,400,000, for Houston $1,182,500.

Ingram, 33, joined the Chiefs in a midseason trade last season with the Pittsburgh Steelers. He had one sack in nine games with the Chiefs and one in six games with the Steelers. He also had two sacks in the Chiefs' three playoff games.
