The Niners have announced two more candidates as possibilities for front office help.

Russ Ball and Lal Heneghan, both experienced NFL personnel executives, are the latest candidates in the 49ers’ search for front-office help.

The two will be brought in for formal interviews with owner John York and Coach Mike Nolan.

Ball has spent 17 years in the NFL, breaking in as an assistant strength and conditioning coach with Kansas City before moving to a front-office position with the Chiefs in 1997. He has been with the New Orleans Saints for the past four years, dealing primarily with cap issues.

Heneghan, an attorney, spent seven years with the NFL Management Council and worked on cap issues and the collective bargaining agreement. As the Cleveland Browns’ vice president of football operations and general counsel in 2003-04, Heneghan helped develop budgets, advised on legal matters and dealt with the salary cap and player contracts.
