Hurst (calf) isn't participating in the portion of Friday's practice that's open to the media, Ben Baby of ESPN.com reports.
The 29-year-old sat out last week's win over the Browns with the calf injury, and he hasn't participated at practice this week. Hurst is trending toward a doubtful or out designation for Sunday's game at Tampa Bay, so Mitchell Wilcox is likely to receive another start.
