TEMPORARY STARTER

Ryan Mallett, who's been starting in place of Flacco for Baltimore, went 6 for 10 for 58 yards in less than a half.

"He will be back for the Bengals game, I promise you that," the coach said. "Do you really care when he's going to practice?"
Ravens kicker Justin Tucker had to undergo concussion protocol after being hit in the neck while trying to make a tackle on a second-quarter kickoff. "It was about trying to make a play," said Tucker, who was cleared to return but stayed on the sideline. Kenny Allen kicked an extra point and a 40-yard field goal in the second half.
BALTIMORE (AP) — The winless Buffalo Bills sent home defensive tackle Marcell Dareus, lost quarterback Tyrod Taylor to injury and made far too many mistakes against the Baltimore Ravens, who remained undefeated in the preseason with a 13-9 victory Saturday night.
Buffalo (0-3) is still looking for its first win under rookie coach Sean McDermott, who's got far more important issues to address, such as the behavior of Dareus and the health of Taylor.
"He's in the protocol at this point. Nothing further at this time," McDermott said.
Dareus was exiled by the Bills before the kickoff for violating a team rule. Buffalo general manager Brandon Beane called the transgression "disappointing" and did not rule out the possibility of further discipline beyond the one-game suspension.
McDermott said: "I'm disappointed. We're disappointed. My hope is he'll learn from this and we'll move forward."
Ravens: Signed as a free agent earlier in the week, C Jeremy Zuttah returned to his familiar spot in the middle of the Baltimore offensive line and could press Ryan Jensen for a starting spot.

CLOSE CALL
Harbaugh bristled when asked to reveal a timetable for Flacco's return. The Ravens have said Flacco will start the season opener against Cincinnati, but it's still uncertain when he will join his teammates on the practice field.
Bills: Fifth-round pick Peterman was the first quarterback summoned after Taylor went down and appears to have locked down the backup role after starting camp behind Yates.
While many of his teammates put their hands on their hearts during the national anthem, Bills tackle Cameron Jefferson raised his right fist. Jefferson has done so previously, saying he's protesting racial inequality.
Backup Nate Peterman went 11 for 23 for 93 yards. Third-stringer T,Antonio Brown Jersey.J. Yates entered in the third quarter and had his first pass intercepted — a turnover that Baltimore converted into a touchdown for a 10-7 lead.
