Monmouth University has declared senior middle linebacker Dan Sullivan ineligible for the 2013 season due to an undisclosed violation of team policy.

In announcing the suspension on Wednesday, Monmouth said Sullivan will continue to practice and can participate in all organized team activities.

The Hawks are joining the Big South Conference for football only this year. Last year, the 6-foot-2, 235-pound Sullivan was named to the Northeast Conference first team.

The two-year starter, a local product out of Manasquan, has 137 career tackles. He was in on a team-high 64 stops, including nine tackles for loss and five sacks, with one interception and one forced fumble last season.
