The Saints and safety Marcus Ball have agreed to terms on a three-year contract, adding depth to a position that was in need of it this offseason.
The team announced the move Wednesday afternoon.
Ball (6-foot-1, 209 pounds) spent the past two years with the Toronto Argonauts of the CFL, amassing 142 tackles, seven sacks and four interceptions, two of which he returned for a touchdown.
He played collegiately at Memphis, where he transferred to from Florida State.
The Saints currently have just Kenny Vaccaro and Jairus Byrd on the roster as safeties. Rafael Bush has been tendered but has not signed a new contract.
Malcolm Jenkins left in free agency for Philadelphia while the team released Roman Harper in February.
