In their search for able-bodied offensive linemen, the Redskins have turned to the defensive side of the ball.

Lorenzo Alexander, a 6-1, 300-pound defensive tackle, is working with the offensive line this week.

Alexander is listed as a backup at right guard on the Redskins' unofficial depth chart this week. He is also listed as a reserve defensive tackle.

He could see action as a two-way player in this Sunday's game against the Arizona Cardinals.

"Now that's gridiron football," Alexander said, relishing the opportunity.

Added head coach Joe Gibbs: "What a heart--that's an example of a guy coming from almost nowhere to really play extremely well. He could play on the offensive line if we need him to, and he has become a real valuable guy."

Alexander impressed coaches last year when he lined up as an offensive lineman on the scout team during practices. He spent the entire 2006 season on the Redskins' practice squad.

"I did a pretty good job [playing offensive line], so they thought I would be able to play both sides," Alexander said.

The last time Alexander was on the offensive line in a game was in high school when he also played both ways.

This time, the competition will be more intense.

"There will be added pressure, but I'll work with [assistant head coach-offense Joe Bugel] and Randy Thomas will help me out, too."

Added Alexander: "It's just another way for me to help the team out. I wish that Randy Thomas and the other guys were healthy because I think it gives us a better chance to win. I'm going to step in there and play to the best of my ability."

To make up for lost time on the defensive side of the ball, Alexander will catch up with defensive coaches for his assignments and touch base with his teammates.

"I've got to know the defensive packages, too, so I have a busy week in terms of watching film and getting ready."

Alexander, who is credited with two tackles so far this season, says he enjoys playing defense because it's aggressive nature fits his personality.

"On defense, it's quicker--you just go," he said. "On the offensive line, you have your feet set and you have to be more patient and wait for [the pass rush] to happen.

"Defense comes more naturally to me because I've played it all my life. Offense comes harder for me because you're more passive than aggressive. It's just something you have to get used to."
