KNOXVILLE, Tenn. (AP) - Tennessee's defense has given up just a handful of big plays this season, but those have cost the Volunteers dearly.
The lone player that had a knack for preventing big plays, safety Janzen Jackson, was dismissed from the team just before the season started. Three games into the season, coach Derek Dooley is still trying to find the most effective combination of players in the secondary.
By Dooley's count, opponents have averaged 3.3 yards for 208 of their 217 plays against the Vols (2-1). The other nine have gone for an average 46.4 yards.
The coaches are hoping for some help from Izauea Lanier, a sophomore junior college transfer, when he makes his first start against Buffalo (1-3) on Saturday. They're also hoping backup safety Brian Randolph will step up.
