The Baltimore Ravens expect linebacker Ray Lewis, who has missed the past four games with a toe injury, to return Sunday night against the San Diego Chargers, a team source told ESPN NFL Insider Adam Schefter.

Lewis returned to practice Wednesday, his first session in nearly a month.

On Tuesday, Lewis was noncommittal on whether he'll play Sunday at San Diego, but said he's "confident" that he'll return at some point this season.

"I'm feeling way better," Lewis told reporters Tuesday at a charity event, according to the Baltimore Sun. "Way better. I thought I had a good chance the last four weeks to play, but the coaches are going to make those decisions. They're just being smart. I don't mind being smart. The warrior side of me of course is always going to want to get back out there."

The Sun reported last week that Lewis was scheduled to return this week against the Chargers. On Monday, coach John Harbaugh said that he's "very hopeful" that Lewis will be able to play Sunday.

"Whenever it's time for me get back on the field, I'm definitely going to get back on there," Lewis said.

The Ravens have gone 4-0 in Lewis' absence.
