Colorado coach Jon Embree identified cornerback as a priority in the 2012 recruiting cycle, but fans of the program had reason to worry recently with just one player at the position committed with signing day approaching.

A sigh of relief came Thursday when John Walker, a 6-foot, 175 pound prospect from Woodson High School in Washington, D.C., committed to the black and gold, Rivals.com reported.

Walker is the second player in the 2012 class from Woodson High School and the third in the past two years. Current Buff cornerback Sherrard Harrington was the first player from the school to join the program last year. Defensive end De'Jon Wilson committed in November. Wilson and Walker are cousins.

Walker might not be the last player from Woodson to join the program.

Kenneth Crawley, another cornerback who was previously committed to Tennessee, is considering coming to Boulder as well.

Walker is the 22nd member of the recruiting class.

He is somewhat unknown as a defensive prospect because he played quarterback at a different high school during his first three years in high school. Walker is scheduled to visit CU on Jan. 20.
