Cornelius Ingram, TE, Florida; torn ACL; out for season. With 34 catches last season, Ingram (above) was one of Tim Tebow's favorite targets. Aaron Hernandez, who caught nine passes as a freshman in 2007, takes over.
Rashaad Jackson, DT, Clemson; torn quadriceps tendon; out until midseason. Jackson, the Tigers' active career leader in tackles for loss (16 1/2), will be replaced by junior Jamie Cumbie, who has five career tackles for loss.
Trinton Sturdivant, LT, Georgia; torn ACL; out for season. Sophomore Kiante Tripp moves over from the right side to replace Sturdivant, who started all 13 games as a true freshman.
