Alabama is losing another assistant coach.

Wide receivers coach Billy Napier is expected to be hired as Arizona State's offensive coordinator, sources told AL.com.

Napier will be reunited with former Tide quarterback Blake Barnett, who transferred to Arizona State in December. Napier is stepping into the position previously filled by new Auburn offensive coordinator Chip Lindsey.

The 37-year old Napier had been Alabama's wide receivers coach since 2013, helping to develop players such as All-American Amari Cooper and All-SEC selections Calvin Ridley and ArDarius Stewart.

Napier was previously the quarterbacks coach at Colorado State in 2012, an offensive analyst for the Tide in 2011 and the offensive coordinator at Clemson in 2009 and 2010.

Napier is the third assistant gone from last year's staff and the second to leave Alabama post-national championship game.

Tight ends and offensive tackles coach Mario Cristobal left for Oregon, where he will be co-offensive coordinator, run game coordinator and the team's offensive line coach. Offensive coordinator Lane Kiffin left in January before the Tide played Clemson to become Florida Atlantic's head coach.
