Ertz (hamstring/rest) is participating at Friday's practice, Dave Zangaro of NBC Sports Philadelphia reports.
Ertz sat out Wednesday's practice before returning in a limited fashion Thursday, and his level of participation for Friday's session remains unclear. The 30-year-old's status will receive additional clarity when the official injury report is released later in the day, but he may be able to avoid an injury designation for Sunday's matchup with the 49ers after practicing two straight days.
