The Washington Redskins could be looking to add another backup quarterback. Free agent Josh Johnson told the Mercury News that he has a visit with the Redskins on Wednesday and that he will meet with the San Francisco 49ers in the coming days as well.

Johnson has served as a backup for Tampa Bay the last four years.

Members of the Redskins brass, including head coach Mike Shanahan, offensive coordinator Kyle Shanahan, general manager Bruce Allen and owner Dan Snyder, all are in Texas, attending Baylor quarterback Robert Griffin III's pro day. But a person with knowledge of the situation confirmed that Johnson will still meet with the Redskins. It was unclear, however, what members of the staff he would meet with.

Drafted out of San Diego in the fifth round of the 2008 draft by the Buccaneers and Bruce Allen, the team’s general manager at the time, Johnson has played in 19 games, starting one of them.

He has completed 96 of 177 of his passes for 1,042 yards for five touchdowns and 10 interceptions.

The Redskins are expected to draft Griffin with the second overall pick in the draft. They now have Rex Grossman, John Beck and Jonathan Crompton under contract. But Crompton spent all of last season on the practice squad. And with Beck — who struggled mightily in his three starts last season — set to make just more than $1 million next season, Washington could be seeking a cheaper, younger alternative for a third-string quarterback.

The Redskins aren’t the only team with prior ties to Johnson, however: San Francisco’s Jim Harbaugh coached Johnson in college.
