Ferguson (ankle) remained sidelined at Thursday's practice, Adam Grosbard of The Orange County Register reports.
Like Ferguson, Colby Parkinson (knee/shoulder) also logged a second straight DNP to begin the practice week. If neither tight end is able to play Sunday against Philadelphia, Tyler Higbee, Davis Allen and rookie Max Klare would be in line for heavy snaps in a Los Angeles offense that uses three-plus tight ends more than any other team.
