Redskins signed No. 71 overall pick Josh LeRibeus to a four-year contract.

A power-blocking guard in June Jones' SMU spread, LeRibeus has moved to center in Washington, practicing there exclusively in OTAs. LeRibeus figures to be a top "swing" interior reserve during his first season. Once he learns to zone block, LeRibeus could push for a full-time role as soon as 2013.

Redskins third-round pick Josh LeRibeus practiced exclusively at center during the team's first rookie minicamp.

LeRibeus was a power-blocking guard at Southern Methodist, but the Redskins are turning him into a zone-blocking center. If athletic enough to execute the transition, LeRibeus could supplant Will Montgomery in a season or two.
