FLOWERY BRANCH — It's too early for the Atlanta Falcons to know how much defensive end John Abraham will play in Sunday's NFC title game. Abraham, the NFL's active sacks leader, made it through just 15 snaps in last week's divisional playoff victory over Seattle before aggravating a left ankle injury that forced him to leave in the second quarter. "You don't want to lose a good player," Falcons defensive coordinator Mike Nolan said.
