Urias (upper leg) is out of the lineup for Monday's game against the Royals, Nathan Ruiz of The Baltimore Sun reports.
Baltimore won't be calling up another infielder in a corresponding move, so the Orioles will be left with a thin bench in Monday's series opener while Urias tends to the upper-leg injury. With Urias unavailable, look for Jorge Mateo to pick up the start at shortstop, while Kelvin Gutierrez mans third base.
