Horsted (concussion) was listed as a DNP on Monday's estimated practice report, Vincent Bonsignore of the Las Vegas Review-Journal reports.
Horsted appears to still be in protocols after suffering a concussion Week 12 against the Seahawks. With the Raiders on a short week following Sunday's win over the Chargers, which Horsted missed, he may have a difficult time gaining clearance and playing Thursday against the Rams.
