Steelers agreed to terms with LS Matt Katula on a one-year contract. 30-year-old Greg Warren is Pittsburgh's primary deep snapper, but he's endured multiple ACL tears. Katula, 29, could push for Warren's job in camp.

Vikings signed LS Matt Katula. Katula has seen time with the Ravens and Patriots the past two seasons. He'll take over for Cullen Loeffler, who will miss 2-6 weeks with a back injury suffered in Week 12.
