The Redskins have agreed to terms with offensive lineman Chad Rinehart, a supplemental selection in the third round of the 2008 draft.

Per the Washington Post, it’s a four-year contract.  Along with a $611,000 signing bonus, Rinehart will earn base salaries of $295,000 in 2008, $385,000 in 2009, $470,000 in 2010, and $555,000 in 2011.

The deal also contains an escalator worth up to $1.2 million for the fourth year.  Such devices are becoming more common, given that a four-year deal prevents the player from reeling in a nice payday as a restricted free agent.

The Redskins have signed five of their ten draft picks.

In other moves, the Redskins released quarterback Sam Hollenbach, who was on the 53-man roster for the final two regular-season games and for the team’s playoff loss to the Seahawks.
