The Ravens said Monday that Neuheisel would continue most of his current duties, including running offensive team meetings and handling the Baltimore quarterbacks.
Billick took over the play-calling duties after he fired offensive coordinator Jim Fassel six games into last season. The offense responded under Billick, winning nine of its last 10 games and posting the second-best record in the AFC. The Ravens, however, lost an NFL playoff game to Indianapolis last weekend when they scored just two field goals in a 15-6 loss.
Neuheisel has 15 years of coaching experience, including the past two seasons in Baltimore. He was the head coach at Washington and Colorado in the collegiate ranks.
