No. 25 Georgia will be without a key defensive lineman as it hosts No. 11 Tennessee in a huge SEC East showdown Saturday.

Freshman David Marshall is not dressed out, according to a report from DawgNation.com, after not participating in practice Wednesday for undisclosed reasons. Marshall started against Ole Miss last weekend, picking up two tackles as the Bulldogs fell 45-14.

He has recorded nine tackles and nine sacks along with breaking up one pass. Marshall’s absence is another blow to Georgia’s defensive line — sophomore Jonathan Ledbetter, a starter during spring practice, is sitting out as part of an indefinite suspension stemming from arrests.

The Bulldogs (3-1, 1-1) and Volunteers (4-0, 1-0) kick off at 3:30 p.m. ET on CBS.
