Head coach Andy Reid said that Thornton (concussion) won't take part in Tuesday's practice, Matt McMullen of the Chiefs' official site reports.
EDGE Analysis
Thornton entered concussion protocol following the Chiefs' Week 15 loss to the Chargers and wasn't available for this past Sunday's loss to the Titans. The wide receiver still appears to be dealing with symptoms of the concussion and is looking unlikely to be available for Thursday's game against the Broncos.
