Morgan, a 6-3, 228-pounder from Canton, Miss., was injured while throwing a block as part of the flying wedge formation on a kickoff return in the first quarter after TCU had taken a 7-0 lead. The game stopped momentarily as Morgan was helped from the field.
Diagnostic procedures revealed Morgan had torn both his anterior cruciate and medial collateral ligaments. Though not a starter, Morgan had been close to a starting position and had seen playing time in each of Vandy's first four games. Morgan redshirted his freshman year, and thus cannot be a candidate for a medical redshirt.
Morgan is the second player this year to suffer a serious injury on a kickoff return. In the previous week's 45-7 loss to Auburn, tight end Dan Murphy suffered a concussion on a similar play and was forced to leave the game.
Vanderbilt employs five blockers, in a tight "wedge" formation, who run interference in hopes of springing the kickoff returner for a big gain. Blockers on the wedge are charged with slowing defenders traveling toward the ball carrier at high speeds, and vicious collisions are often the result.
Asked Saturday if the Commodores would consider altering their strategy after suffering two serious injuries in two weeks, head coach Bobby Johnson said he was committed to using the wedge. "We're not changing it," he said.
