Davis (back) practiced in full Wednesday, the Sacramento Bee reports. Davis was unhindered in practice for the first time since sustaining a bruised left ankle in Week 2. Along the way, back spasms started to afflict him, and he appeared in just two of four games during that stretch. As long as a setback is avoided, he should be active for a second consecutive outing Sunday in Denver, who have surrendered 10.5 YPC and two touchdowns to opposing tight ends through five contests.
