Glavine complained of coldness in his left middle finger after his start Aug. 16 at Philadelphia. An angiogram determined the symptoms were caused by an old injury and not a significant blood clot in his pitching shoulder.
Glavine will be treated with blood thinners and medication to help circulation.
"The news from our doctors is a good as we could have hoped for," Mets general manager Omar Minaya said. "We look forward to having Tom return to full activity and get back on the mound as soon as possible."
Glavine, 12-6 with a 3.92 ERA and 287 career victories, will miss at least two starts, Tuesday's and this weekend against Philadelphia.
"I was relieved to hear the news," Glavine said. "First and foremost to hear that the condition is not serious, but also to hear that I can get back to doing what I love to do relatively quickly."
REPLAY: In what could be a playoff preview, the Mets overcame a six-run deficit powered by two Albert Pujols homers to beat St. Louis 8-7 Tuesday night, winning on Carlos Beltran's walk-off, two-run homer in the ninth inning off Jason Isringhausen.
Carlos Delgado homered twice for the Mets, including the 400th of his career, a grand slam in the fifth inning.
Seeking to beef up their outfield, the Mets acquired OF Shawn Green and $6.3 million from the Diamondbacks for minor league LHP Evan MacLane. The Mets outfield has been shaky since the July 31 trade of Xavier Nady to the Pirates. Rookie OF Lastings Milledge has been inconsistent in his big-league trials, and LF Cliff Floyd has been out since Aug. 9 with a sore Achilles tendon.
Green is expected to see the majority of action in right field.
Green, who has hit more than 40 homers in a season three times, was batting .283 with 11 homers and 51 RBIs this season for Arizona. He had lost playing time recently to rookie OF Carlos Quentin.
The money the Mets are receiving will help offset the guaranteed salary Green is owed for the remainder of this year and next year. Green will make $9.5 million in 2007.
LHP Tom Glavine's injury is not as serious as was speculated, and he will not need surgery to remove a blood clot in his pitching shoulder. Glavine could pitch again in a week to 10 days. He will be treated with blood thinners and medication to improve circulation.
The Mets announced they have completed all agreements on financing and development for their new stadium, set to open in 2009.
C Ramon Castro, on the disabled list with a sore left ribcage muscle, sustained a strained left knee and torn medial meniscus Monday night while stretching in preparation for a rehab assignment at Class A Brooklyn.

LF Cliff Floyd, on the disabled list with a sore Achilles tendon, has resumed workouts at the Mets' spring training facility in Port St. Lucie, Fla.
1B Carlos Delgado homered twice Tuesday, including the 400th of his career, to become the fourth player in history to hit 30 or more homers in 10 consecutive seasons. He joins Barry Bonds (13 in a row), Jimmie Foxx (12) and Sammy Sosa (10).
LHP Royce Ring was optioned to Triple-A Norfolk to clear a roster spot for newly acquired RHP Guillermo Mota. Ring had no record and a 2.25 ERA in four games with the Mets.
The Mets received good news Tuesday: Left-hander Tom Glavine's condition is not believed to be serious, and he might resume pitching in a week to 10 days.
