The Cardinals extended a tender Wednesday to Dortch, who is a restricted free agent, Darren Urban of the team's official site reports.
Dortch has become a mainstay in Arizona's passing game the last three campaigns, averaging a 37.7-363-2.3 line on 51.7 targets per year while missing just two games during the regular season. The team will have the right of first refusal for any contract offer that he receives, but if he returns to the Cardinals, he'll continue to operate as the third wide receiver behind Marvin Harrison and Michael Wilson (hamstring).
