"He won't miss any training camp or anything like that," Frazier said after Tuesday's open organized team activity practice at Winter Park.
"Just wanted to get it done right now, rather than run into a situation where we get to camp and it continued to bother him and we had some issues we'd have to deal with that there."
According to a source informed of the injury, Greenway had some residual fraying of the meniscus in the knee. It's expected to be an easy cleanup job, and recovery should take only a few weeks.
Greenway, 30, never appeared on the injury report last season while leading the team in tackles (191, including 121 solo) for the fifth consecutive season.
He practiced during the open OTAs the past two weeks, but Frazier said he had been feeling "a little tension" and "some tenderness" in the knee.
"We ended up doing an MRI and saw some things in there we thought we needed to go in and clean up," Frazier said. "That's what we're going to do, have a scope to get it done."
Peterson, Jennings also miss practice
Halfback Adrian Peterson also missed Tuesday's practice. But Frazier said that was strictly a coach's decision, and Peterson said he expected to practice on Wednesday.
"Everything went good, just me getting a day off," Peterson said. "Relax, let the body rejuvenate a little bit. I think I did more work in there than I would out here, so it's all good, feeling good. ...
"I did upper body work out, pretty intense upper body workout, get treadmill going a little bit. I guess you could say it was a day off when it really wasn't."
Receiver Greg Jennings is absent this because of a personal issue, Frazier said, but should return for next week's mandatory three-day minicamp.
Also sitting out were: center John Sullivan (knee), cornerback Jacob Lacey (thumb), receiver Greg Childs (knees), end Jared Allen (shoulder/knee), safety Darius Eubanks (hamstring), linebacker Nathan Williams (ankle) and linebacker Michael Mauti (knee).
Lacey, who underwent surgery last week after dislocating the thumb, watched practice with his left arm in a sling. Childs, who is coming off bilateral patellar tendon tears, ran routes and caught passes on the side after practice.
