Redskins guard Kory Lichtensteiger has agreed to a five-year contract to remain in Washington. The monetary amount was not yet known, but his return helps solidify the offensive line and keeps him off the free agent market. Lichtensteiger tweeted the news Saturday night and is expected to sign the deal Sunday or Monday. There are no voidable years in the contract, according to a league source.

Lichtensteiger started all 16 games this past season, one season after undergoing surgery to repair a torn ACL and MCL. Lichtensteiger is considered a good fit in the Redskins zone-blocking scheme because of his ability to run and his understanding of angles.

But it was uncertain how much the Redskins would invest at guard considering they drafted two last season in Josh LeRibeus (third round) and Adam Gettis (fifth round). They also signed Chris Chester in free agency in 2011. Chester, who counts $4.3 million against the salary cap and has a $3 million salary in 2013, could be a candidate for a restructure, but a source with knowledge of the situation said he had not yet been approached about re-doing his contract. Lichtensteiger’s deal likely is spread out over five years to ease the cap hit.

The Redskins still want to get deals done with linebacker Lorenzo Alexander and tight end Fred Davis. They have been telling people  for a couple weeks that they expect to retain Davis. They also would like to re-sign Alexander, but no deal was imminent as of late Saturday night. Also Saturday, they re-signed tight end Logan Paulsen and fullback Darrel Young and agreed to terms with linebacker Rob Jackson.

The Redskins remain in discussions with right tackle Tyler Polumbus, but nothing was imminent.
