The Denver Broncos announced that sixth-round offensive lineman Eric Olsen has signed his rookie contract.

Financial terms of what's believed to be a four-year contract were not disclosed.

The 183rd overall pick of the 2010 NFL Draft out of the University of Notre Dame, Olsen (6-4, 306) started his final 31 games for the Fighting Irish, including 12 starts at center during the 2009 season. Olsen started 13 games at left guard in 2008, and six games at right guard during the 2007 season.

Olsen is expected to begin his NFL career at guard, but figures to be in the mix for the team’s starting center job. Olsen is not very mobile, but the Staten Island, New York native, and son of a New York City firefighter, plays with a high-level of nastiness. Olsen did 35 reps on the bench press at the Combine, making him an ideal fit for the Broncos’ power blocking scheme.

Olsen is the fifth member of the Broncos' nine-player 2010 draft class to sign. First-round wide receiver Demaryius Thomas and quarterback Tim Tebow, along with second-round offensive guard Zane Beadles and third-round wide receiver Eric Decker, remain unsigned.
