49ers signed K Matt Gay, formerly of the Commanders.

Eddy Piñeiro suffered a hamstring injury in Week 11 and is expected to miss some time. Gay will take his place in the lineup for now. The Commanders cut Gay on Monday after he missed two field goals versus Miami. Gay has missed six field goals on 19 attempts this year. All but one of his misses have come from 50 yards out, so the 49ers may only send him onto the field for short kicks.
