49ers Sign DE Clelin Ferrell to Active Roster After Recent Elevations

The San Francisco 49ers have signed defensive end Clelin Ferrell off the practice squad to fill a roster spot. Ferrell has been a recent contributor for the team, having appeared in the last three games as a temporary practice squad elevation. This move comes as the 49ers adjust their roster, including waiving quarterback Adrian Martinez, ahead of their Sunday game against the Cardinals. Ferrell's signing provides additional depth and experience to the team's defensive line.
