Lock (ribs) will return to a limited practice Thursday, Zac Stevens of TheDNVR.com reports.
Per James Palmer of NFL Network, Lock -- who didn't practice Wednesday -- is in line to see some reps during the team portion of practice Thursday. While the QB's return to the field bodes well for his chances of suiting up Sunday against the Dolphins, Lock will have to escape practice (both Thursday and Friday) without any setbacks in order to garner the start this weekend.
