Lamb (concussion) was a full participant in Wednesday's non-padded practice and now needs joint clearance from a club physician and an independent neurologist to play in Thursday's game against the Raiders, Michael Gehlken of The Dallas Morning News reports.

Pending the results of his upcoming examinations, Lamb appears to be trending toward playing Thanksgiving Day, just four days after being diagnosed with a concussion. The Cowboys presumably will list him as questionable on their final weekly injury report, but Lamb's status may ultimately be known well before the team's 4:30 p.m. ET kickoff Thursday.
