The NFL lifted Givens' roster exemption Thursday.
Givens now returns to the fold after missing the 49ers' Week 14 loss to Washington while attending to a personal matter. The Penn State product earned his first career NFL start Week 12 against the Rams, collecting a fumble recovery in that contest. Givens may be right back in the lineup Sunday against Dallas, as starting defensive tackle D.J. Jones continues to deal with an ankle injury.
