Former Ravens starting strong safety James Ihedigbo has joined the Detroit Lions.

It's a two-year contract, according to a source.
Ihedigbo has been negotiating with the Lions since late last week and agreed to terms tonight.

"It's Agreed upon! I'm a @DetroitLionsNFL," Ihedigbo wrote on his Twitter account. "I'm excited for what's ahead and helping this team achieve greatness!!! #HeartOfALion #LionsNation."

The Ravens agreed to a one-year contract with former St. Louis Rams safety Darian Stewart on Friday as they opted not to match offers for Ihedigbo.

Ihedigbo, 30, had a career-high 101 tackles and three interceptions last season.

He visited the Lions last week.

Now, he's reunited with Lions defensive coordinator Teryl Austin, his secondary coach the past two seasons in Baltimore, and Lions head coach Jim Caldwell, the former Ravens offensive coordinator.
