After hiring offensive coordinator Greg Roman away from the San Francisco 49ers on Tuesday, the Buffalo Bills now want to bring in at least one of his staff members.

According to CSN Bay Area's Matt Maiocco, the Bills have requested permission to interview 49ers offensive line coach Mike Solari for the same job in Buffalo.

Pat Morris coached the Bills' offensive line the past two seasons under Doug Marrone. Buffalo's line was the league's third-worst this season by Pro Football Focus' tracking.

The development of 2014 second-round pick Cyrus Kouandjio will be key for whomever coaches the Bills' offensive line next season. Kouandjio performed poorly in the preseason and was active for just one regular-season contest.

Solari, 59, has coached in the NFL since 1992. He served as the Kansas City Chiefs' offensive coordinator from 2006-07.
