Patriots defensive tackle Vince Wilfork, who sprained his ankle during Sunday’s game against the Falcons, might miss the Week Four visit from the Ravens.
Wilfork has practiced neither Wednesday nor Thursday.
Linebacker Jerod Mayo, who injured his knee during the Week One game against the Bills, also has not practiced this week. (Mayo is expected to miss several more weeks with a Grade III sprain of the MCL.)
Limited participants for the Pats in each of the last two days have included cornerback Darius Butler (thigh), tackle Nick Kaczur (ankle), receiver Randy Moss (back), receiver Matthew Slater (elbow), cornerback Shawn Springs (knee), receiver Wes Welker (knee), cornerback Jonathan Wilhite (groin), and defensive tackle Mike Wright (shoulder).
Quarterback Tom Brady (shoulder) has fully participated both days.
