It'll be girls vs. boys, all for a good cause, at Skyline High School on Friday.

The two Skyline lacrosse programs will go head-to-head in both junior varsity (5:30 p.m.) and varsity (7 p.m.) matches at the school's stadium. Tickets are $5 and benefit the Vada Murray Fund for Cancer Research.

Vada Murray, a former Michigan football player and a longtime Ann Arbor police officer, died April 6, 2011, at age 43 of lung cancer.

Ann Arbor Police Chief John Seto and Vada Murray's wife, Sarah Murray, will coach the lacrosse teams. Players will exchange sticks at midfield before the game and play women's lacrosse rules.
