The four-time Pro Bowl wide receiver later confirmed the news on Twitter.
I signed my tender today. I love the game and I love my teammates! Hopefully doing the right thing gets the right results. #leapoffaith

The signing comes one day after Welker, who wants a long-term deal, told WEEI Radio he had "$9.5 million reasons why I won't miss any regular-season games." The Patriots have organized team activities next week, but Welker isn't required to report to the team facility until a full-squad minicamp in mid-June.
Welker didn't participate in the Patriots' voluntary workout program last month.
"Through my body of work, through the past five years, I think what I've done -- I've earned a long-term deal," Welker told ESPNBoston.com in April. "It's what I am looking for and what I want. Hopefully that's the case, and hopefully we come to something where we can make that happen."
Welker, a nine-year NFL veteran, has played the last five seasons in New England. He caught 122 passes for 1,569 yards and nine touchdowns in 2011.
