After falling outside of his South Florida home days before training camp opened, McKinnie said he suffered back spasms. He said he was told to rest instead of potentially aggravating it by riding on a plane for more than two hours.
"I went to the chiropractor and he called up here and told (the Ravens) that they were giving me treatment until he felt like I was well enough to get on a plane," McKinnie said.
Complicating matters is thatt McKinnie is reporting a weight of 360 pounds. McKinnie had been down to 354 in May but said the time spent injured hurt him. His goal this offseason was to get to a playing weight of 348 pounds.
He expressed frustration that he's had to battle weight issues for the past three years and that he's meeting with a specialist Monday to figure out what he can do to drop the additional weight.
"I don't know how to diagnose it until I find out on Monday," McKinnie said. "It's just to better help me with my whole weight thing because this wasn't an issue my whole career until about three years ago, in '09. I think there's kind of like an imbalance or something maybe that is going on with metabolism. We're going to try and work on it."
McKinnie spent the past two practices participating in individual drills and will fully participate when Baltimore returns to practice Monday. He said his back feels fine and that he doesn't anticipate any setbacks.
"If you all check my track record, I don't stay injured at all," he said. "I don't miss games with injuries and stuff like that. The whole being injured thing wasn't a big deal to me. It's just how fast I could recover. I'll be ready by next week or whatever.”
Ngata full-go on Monday: DT Haloti Ngata will fully participate in Monday's practice after recovering from a hamstring injury suffered the day he reported to camp.
"I'll be fresh," Ngata said. "The guys will hopefully get some rest tomorrow and get ready for practice."
Ngata said he's about 345 pounds, 10 more than what he played at a season ago. He wanted to gain the weight to add the power he thought he lost as 2011 wore on.
"I can feel the power," Ngata said. "We'll just see how it goes. As the season goes, if I feel like I need to lose the weight, then I'll probably try to lose the weight during the season."
Dickson, Blackstock injured: TE Ed Dickson was poked in the eye during Saturday's practice and couldn't finish. Coach John Harbaugh expects him to be fine. LB Darryl Blackstock aggravated a groin injury and left practice. It's not expected to be serious.
Haloti Maximus: This past week, Ngata and his wife Christine welcomed a new addition to their family, son Haloti Maximus.
Yes, you read right -- they named their son Haloti Maximus. But it's for good reason: Haloti Maximus entered the world weighing 10 pounds, 10 ounces.
"He was just huge," Ngata said. "We thought it fit him. We both thought it would be a good name and went with it."
Could Haloti Maximus follow in his father's footsteps and be a future DT?
"He probably will be," Ngata said. "He's a lot bigger than my oldest (son)."
