Cornerback Terrail Lambert worked out Tuesday for the Rams and will be added to the practice squad. He joins defensive tackle Jimmy Saddler-McQueen, who was signed Monday to the practice squad.

Lambert, 24, signed with San Francisco in 2009 as an undrafted rookie out of Notre Dame but spent most of last season on the Indianapolis practice squad. He was released by the Colts at the end of the 2010 preseason. At Notre Dame, Lambert started 31 games and had four career interceptions, one of which he returned for a game-winning touchdown against Michigan State.

Saddler-McQueen was signed last April by Chicago as an undrafted rookie from NCAA Div. II Texas A&M-Kingsville. He spent most of training camp and the preseason with Dallas before getting released by the Cowboys. Saddler-McQueen recorded a forced fumble in his first exhibition game with the Cowboys and had a safety later in the preseason against San Diego.

The Rams released fullback Jamie McCoy to make room for Saddler-McQueen. It was not clear what accompanying move would be made to free up a practice squad slot for Lambert. But with cornerback Kevin Dockery sidelined again with a hamstring injury, it's possible Marquis Johnson could be promoted to the active roster — as was the case last month.

Also on Tuesday, former Rams cornerback Quincy Butler paid a free-agent visit and took a physical but was not signed.
