Howard declined to give details Thursday morning and the team says it has nothing to announce.
He is in the second season of a two-year, $4.5 million deal.
The 29-year-old Howard is the first goalie in franchise history to win at least 35 games in each of his first three full seasons. He is 16-12-4 this year, his fourth full season in net, entering a possibly pivotal game Thursday night against the San Jose Sharks.
Detroit is clinging to eighth place in the Western Conference and is hoping to close the season well enough to make a 22nd straight post-season appearance.
Howard says he's focused on helping the Red Wings be in the playoffs.
