According to the Houston Chronicle and Brazos County Sheriff's office records, Walker, a potential starter and definite contributor, was booked a little after 10 p.m. Friday night on "charges of assault causing bodily injury to a family member, and interfering with emergency requested for assistance."

The College Station Police Department has indicated that a dispute between Walker and his girlfriend, whom he reportedly pushed down, led to the arrest.

Texas A&M has been able to avoid the negative headlines for the most part this offseason. After the dramatic departures of two talented quarterbacks in Kyle Allen and Kyler Murray, the quiet has been a welcome change around College Station.

Walker appeared in 11 games last season and has started in five contests during his two years since joining the Aggies as a four-star prospect coming out of Gilmer, Texas, in the Class of 2014. The former U.S. Army All-American has 45 career tackles and is now back home, according to Sumlin.

While Walker's role in the 2016 Aggies defense was to be determined, it's still a position of concern for the fall given how porous the group was against the run a season ago. With stars like Myles Garrett, Daeshon Hall and Daylon Mack up front, Armani Watts on the back end of the defense and John Chavis leading the group, there's reason to believe Texas A&M should be more dominant than last year's numbers suggest.
