In 2007, Kendall became embroiled in a contract dispute with the Jets' front office. Kendall believed the team had reneged on a verbal agreement to raise his base salary for 2007 after he had agreed to restructure his contract the year before. Kendall made his grievances public despite head coach Eric Mangini's instructions not to do so. As a result, Mangini sent Kendall to the rookie dorms and demoted him to second string, further aggravating the situation. On August 23, 2007 Kendall was traded to the Washington Redskins for a conditional draft pick (either a fifth round pick in 2008 or a fourth round pick in 2009, based on playing time). He became a free agent after the 2008 season.
