Phil Richards of the Indianapolis Star reports Indianapolis Colts restricted free agent offensive tackle Charlie Johnson has signed his one-year tender.

Johnson was tendered at the "Second Round" level, and will earn a $1.759 million dollar salary in 2010.

A sixth-round pick (199th overall) in 2006 out of Oklahoma State, Johnson has started 39 games for the Colts over the last four seasons, and four of the Colts' nine playoff games, including Super Bowl XLIV.

Johnson is the fourth Colts restricted free agent to his one-year tender, joining safety Melvin Bullitt and defensive linemen Antonio Johnson and Daniel Muir. Safety Antoine Bethea has yet to sign his tender.
