Source: Josh McDaniels returning to Pats

With offensive coordinator Bill O'Brien agreeing to become Penn State's next head coach, New England now is expected to hire Rams offensive coordinator Josh McDaniels as an offensive assistant coach, according to an NFL source.

ESPN's Adam Schefter reports McDaniels will likely succeed O'Brien as the Patriots offensive coordinator next season, but he was to begin working immediately for the Patriots this season, returning to the team he left to take a head coaching job with the Broncos in 2009, the source said.

O'Brien will work as the Patriots offensive coordinator for the remainder of this season.
