Vontae Davis will go through concussion protocol

INDIANAPOLIS -- Observed and heard in the Indianapolis Colts' locker room after their 49-27 victory over the Washington Redskins at Lucas Oil Stadium.

Davis dealing with concussion: Colts coach Chuck Pagano said Vontae Davis will have to go through the NFL's concussion protocol before he can be cleared to play. Davis suffered the concussion in the third quarter when he bounced off Redskins running back Roy Helu. Davis remained on the ground for several minutes before walking off the field. The Colts can't afford to be without Davis, their best cornerback, for an extended period of time because there's a drastic drop-off between him and Josh Gordy, who replaced Davis in the lineup. Gordy was beaten by Redskins receiver DeSean Jackson for a touchdown later in the series after replacing Davis. Gordy was also called for pass interference defending Jackson later in the game.

Case of the fumbles: Colts running back Daniel Herron likely would have had the team's first 100-yard rushing game since the 2012 season if he had held on to the ball. Herron lost a fumble for the second time in as many games in the second quarter. "Have to keep working on it," Herron said. "It's one of those things. You hate for it to happen. You just have to keep working on it in practice. Make sure the guys are going after the ball [in practice]. Keep it high and tight. It's terrible it happened again. I hate it, but you have to learn from it and keep moving forward." Herron finished with eight carries for 88 yards, including a 49-yard touchdown run.

Cribbs fitting right in: Return specialist Josh Cribbs, who signed with the Colts two weeks, averaged 31.2 yards on his five kickoff returns to help give the offense solid field position.
