The Redskins have retained another one of their restricted free agents, signing fullback Darrel Young to a deal Saturday afternoon, a person with knowledge of the situation said.

Young’s contract includes a $1 million signing bonus and, including incentives, could earn him up to $6.2 million over three seasons.

Signed as an undrafted linebacker out of Villanova in 2009, Young made the switch to fullback during Mike Shanahan’s first offseason with the team.

After working behind veteran Mike Sellers in 2010, Young took over as the starter in 2011.

Young last season recorded 14 carries for 60 yards and eight catches for 109 yards and two touchdowns. He also is one of Washington’s top special team’s coverage players.

The Redskins could have retained Young under a one-year restricted free agent tender for roughly $1.3 million, but the way this longer-term deal is structured, his salary for 2013 will be more cap-friendly for Washington.

Earlier today, Washington re-signed tight end Logan Paulsen, also to a three-year deal.
