Los Angeles Rams quarterback Matthew Stafford has cleared concussion protocol but will sit out Sunday's game against the Seattle Seahawks, coach Sean McVay said on Friday.
It will be the second consecutive game and third this season that Stafford misses.
John Wolford will start at quarterback against Seattle and Bryce Perkins will be the backup.
McVay said Stafford cleared the protocol on Friday, but the team is still looking for further information about the neck injury Stafford sustained in Week 11 against the New Orleans Saints.
Stafford, 34, played against the Saints after clearing protocol from a previous concussion.
