N.F.L. Roundup - 49ers Will Stick With Kaepernick at Quarterback San Francisco Coach Jim Harbaugh is staying with Colin Kaepernick as his starting quarterback as his team prepares for Sunday's home game against Miami. But Alex Smith is not out of the mix. A day after a 16-13 overtime loss at St. Louis, Harbaugh accepted the blame for the fourth-quarter pitch that was fumbled by Kaepernick and led to Janoris Jenkins's 2-yard fumble return for a touchdown. The ensuing 2-point conversion tied the score. Harbaugh did not call the play, but he relayed it through the headset to Kaepernick. Harbaugh said he saw positives in the way Kaepernick, a second-year player, responded after the mistakes. BOUNTY HEARINGS RESUME Hearings in the N.F.L. bounty investigation of the Saints have resumed with witness appearances by the former Vikings coach Brad Childress, the Saints assistant head coach Joe Vitt and linebacker Jonathan Vilma. The former commissioner Paul Tagliabue has been appointed to oversee the hearings. EAGLES MAKE MOVES Nick Foles is the quarterback of the present for Philadelphia, and Jim Washburn is the defensive line coach of the past. Coach Andy Reid said Foles would remain the starter for the rest of the season, even when Michael Vick returns from a concussion. The Eagles (3-9) have lost eight straight games. Reid made the announcement a day after Foles had his best performance in a 38-33 loss at Dallas on Sunday night. Foles, a third-round pick, has started the last three games since Vick was injured on Nov. 11. Also Monday, the team fired Washburn in its latest coaching shake-up. Reid dismissed Washburn hours after the loss. The former defensive line coach Tommy Brasher will replace Washburn. It was the third major move on defense in seven weeks. The defensive coordinator Juan Castillo was fired on Oct. 16. The two-time Pro Bowl defensive end Jason Babin was released last week. COACH LEAVES RAIDERS Coach Dennis Allen left the Raiders after Sunday's 20-17 loss to Cleveland to be with his father, who has a serious medical issue. Allen is expected to rejoin the team on Wednesday night and be on the field Thursday when the Raiders (3-9) host the Broncos (9-3). Until then, the offensive coordinator Greg Knapp will oversee the team's preparations.
