Davis, who sat out last week with a hyperextended elbow, was waived with an injury designation. He already had been ruled out to play Sunday against the Los Angeles Rams. He became expendable because the Jets have three other tight ends on the roster -- Brandon Bostick, Austin Seferian-Jenkins and recently-acquired Eric Tomlinson.
Davis actually played in 56 percent of the offensive snaps in the first quarter of he season, but his role gradually decreased, as he lost time to Bostick. Davis played in eight games and -- this is hard to believe -- had no receptions. In 24 games with the Jets, he caught only three passes.
McDougle's promotion makes sense because nickel back Marcus Williams (sprained ankle) will be sidelined multiple weeks. McDougle was a third-round pick in 2014, but he has battled injuries and has appeared in only 15 games.
The Jets also re-signed linebacker Victor Ochi to the practice squad.
