Broncos sign S Darian Stewart

Englewood, CO ( - The Denver Broncos have agreed to terms with safety Darian Stewart on a two-year contract.

Stewart is expected to replace Rahim Moore as the starting free safety. Moore departed the Broncos via free agency to sign a three-year deal with Houston.

The 26-year-old Stewart spent his first four seasons in the NFL with the St. Louis Rams before he joined Baltimore in 2014. Last season, he started a career-high 14 games and had 53 tackles, one interception and one forced fumble.

The Broncos also came to terms with free-agent guard Shelley Smith on a two- year deal. A 2010 sixth-round draft choice by the Texans, Smith spent two years in Houston before joining the St. Louis Rams (2012-13). He played in 11 games for Miami last season.
