The Eagles have agreed to sign Demetress Bell to a five-year contract to help fill the void of Pro Bowl left tackle Jason Peters. Peters ruptured his Achilles tendon late last month while working out in Texas. Bell, a seventh-round pick of the Bills in the 2008 draft, started 30 games at left tackle for the team. He previously had spelled his first name "Demetrius" but the Eagles made note of the proper spelling in the statement announcing they had agreed to terms on a contract.
