No Kenny Phillips or Jason Peters here Tuesday.

Last week veteran safety Kenny Phillips spoke about easing his knee back into football shape and being ready when training camp and the regular season started.

Today Phillips was sidelined with a knee injury per Chip Kelly who declined to be any more specific. Phillips is coming off a sprained medial collateral ligament in his right knee. In 2009 he had microfracture surgery on the left knee.

An Eagles spokesman said it was the left knee that was giving Phillips trouble and that he was being backed off it as a precautionary measure.

Also missing from work Monday was left offensive tackle Jason Peters. Unbeknownst to media, Peters wasn't around last week, either, according to Kelly although a spokesman thought Peters had returned after experiencing travel difficulties due to bad weather. Peters is taking care of personal business per a league source.

Kelly basically said only that Peters' absence wasn't injury related. Organized team activities are voluntary.

Right tackle Dennis Kelly moved to left tackle for practice, with rookie first-round pick Lane Johnson taking snaps at right tackle.

"It was good, it felt good to get into a rhythm," Johnson said. "I went with the ones today and I had to help out with the threes, too, sometimes It wasn't too bad. They've seen me do well out here. They just want to see me use my hands more."

Johnson declined comment when asked if his elevation to the first team was planned.

"I have no clue," he said. "(Coach Jeff Stoutland) told me what to do and I went out there."
