MINNEAPOLIS -- The Minnesota Vikings appear to be bringing in some competition for long snapper Cullen Loeffler, and they'll do it by dipping into punter Jeff Locke's past.

Former Ravens long snapper Kevin McDermott, who played with Locke at UCLA, will sign a two-year deal with the Vikings, according to a league source. The 25-year-old, who played seven games for Baltimore last year after playing 16 for San Francisco in 2013, will get the chance to battle with Loeffler, the Vikings' longtime long snapper who is returning for his 11th season.

The 34-year-old Loeffler signed a new one-year, $1.05 million deal with the Vikings on March 12, but it was worth noting the Vikings opted not to give Loeffler another multi-year deal, instead using one of their veteran minimum salary benefit designations on him. He got a $220,000 base salary guarantee and an $80,000 signing bonus, but counts just $665,000 against the salary cap. Loeffler's low snap late in Week 16 led to a blocked punt and a decisive safety in the Miami Dolphins' 37-35 win. Now, with McDermott's arrival, Loeffler's roster spot doesn't seem to be guaranteed for 2015.
