The Atlanta Falcons listed Brent Grimes as questionable for their wild-card playoff game at the New York Giants after the starting cornerback practiced Friday for the first time this week. Grimes has missed four of the past five games because of a sore right knee. The 2010 Pro Bowl alternate pick underwent minor surgery in late November and didn't return until the Falcons' blowout loss Dec. 26 at New Orleans.
