Who are you betting on: Jordy Nelson or Brian Urlacher?

The two retired NFL greats are getting in on the Packers-Bears rivalry fun by leading members of the military in football drills for a little friendly Green Bay vs. Chicago competition before the two teams open the NFL season on Sept. 5.

It’s happening Tuesday at Naval Station Great Lakes boot camp in North Chicago as part of USAA’s Salute to Service NFL Boot Camp.

Recently retired Packers wide receiver Nelson and Urlacher, the Bears linebacker inducted into the Pro Football Hall of Fame last year, will help military service members train like NFL athletes by putting them through such drills as the 40-yard dash, vertical jump, three-cone shuttle, receiving gauntlet and the QB Arm Challenge.

It will be the seventh NFL boot camp that the financial service company has hosted this season and the first in the Chicago area.
