If the report is true, Chris DiSanto would work as an assistant under Brad Roll, who was hired as the team's strength and conditioning coach a couple of weeks ago. DiSanto is actually re-uniting with Roll, as the two worked together on the Oakland Raiders from 2008-2011 in the same capacity. This past season, DiSanto was the assistant strength and conditioning coach at California. On his profile at the Golden Bears website, it specifically cites DiSanto's work with the special teamers in Oakland:

[DiSanto] was responsible for the core development training of the team's specialists including placekicker Sebastian Janikowski, punter Shane Lechler and long snapper Jon Condo.
