ALAMEDA Several teams around the league have responded to subpar play this season by making changes among their assistant coaches. Raiders coach Dennis Allen doesn't see the need to go that route.
Allen said Monday in his weekly news conference that the evaluation process for everyone is ongoing.
"I'm not going to stand up here and say we're making wholesale changes," Allen said. "We're going to look at every aspect of what we do offensively, defensively and the kicking game and if we feel changes need to be made, we'll make those changes."
Allen said his team's defensive play, in particular, has been disappointing lately. The Raiders fix one issue, then another surfaces.
Sunday, it was the pass defense. Ravens quarterback Joe Flacco passed for 341 yards and three touchdowns in Baltimore's 55-20 win. A week earlier, the Buccaneers rushed for 278 yards and four touchdowns.
"If a guy is wide open, running down the middle of the field, most times that's not a physical problem," defensive tackle Tommy Kelly said. "It just means somebody's not covering him."
Several times, Flacco found receivers wide open as a result of blown coverages or players late responding.
Allen deemed the defense's performance Sunday "unacceptable." The Raiders have allowed 97 points in the past two games.
Bears Coach Lovie Smith said quarterback Jay Cutler is feeling "a lot better" after suffering a concussion against Houston, but he declined to speculate on Cutler's status for Monday night's game against the 49ers.
Smith said the team believes Cutler suffered the concussion when he was hit by Texans linebacker Tim Dobbins with just under three minutes before halftime.
Eagles Quarterback Michael Vick's already uncertain future with the team was placed further in doubt after he was diagnosed with a "pretty significant" concussion. He suffered the injury in Sunday's loss to Dallas.
Bills Coach Chan Gailey said running back Fred Jackson has been diagnosed with a concussion and has been ruled out of Thursday's game against Miami.
Panthers Coach Ron Rivera announced the team fired special-teams coordinator Brian Murphy one day after Carolina surrendered a 76-yard punt return for a touchdown to Trindon Holliday in a 36-14 loss to Denver.
Falcons Atlanta released defensive end Ray Edwards one day after its first loss of the season. Edwards started four of nine games this season, recording nine tackles and no sacks.
Buccaneers Linebacker Quincy Black is expected to recover from a neck injury suffered against San Diego, but he is experiencing complications with his left arm.
