The Citadelís leading tackler, linebacker Carl Robinson, will miss the rest of the football season after tearing the anterior cruciate ligament in his knee.

Robinson suffered the injury during last weekís 28-10 loss to Chattanooga and will undergo surgery later this month. An MRI exam revealed the extent of the injury Tuesday.

A 6-1, 240-pound sophomore from Irvington, Ala., Robinson led the Bulldogs with 54 tackles through five games, with 2.5 tackles for loss and two forced fumbles.

He will be replaced in the starting lineup for Saturdayís game at Samford by Ian Thompson, a 5-10, 215-pound sophomore from Stratford High School. Thompson has played in all five games this season with nine tackles.

The Citadel (3-2, 2-1), ranked No. 22 in FCS, plays at Samford (4-1, 2-1) at 3 p.m. Saturday in a Southern Conference matchup.
