Broncos bolster defensive depth with signings of S Shamarko Thomas and DL Niles Scott

The Denver Broncos were busy on the weekly Tuesday off day, making several minor moves on defense.

The Broncos signed safety Shamarko Thomas to the active roster and signed defensive lineman Niles Scott to the practice squad. The team also released nose tackle Kyle Peko and defensive end DeShawn Williams from the practice squad.

The moves come a day after Denver released wide receivers Isaiah McKenzie and River Cracraft, and activated wide receiver Carlos Hernandez to the active roster.

Thomas, 27, has played 60 games with Pittsburgh and Buffalo since 2013. He spent preseason with Indianapolis and Denver. The 5-foot-9, 205-pound Thomas was a fourth-round pick of Pittsburgh in the 2013 NFL Draft out of Syracuse.

Scott, a rookie out of Frostburg (Md.) State University, was in training camp with San Francisco and was on the 49ers practice squad.
