JACKSONVILLE, Fla. (AP) - Terrance Knighton and Tyson Alualu have been fixtures as starters at defensive tackle for the Jacksonville Jaguars for two years.
Knighton has started all but three games the last three years. Alualu hasn't missed a start since the Jaguars made him their No. 1 pick in the 2010 draft.
Things could be different this year.
Both are being challenged for their jobs by a pair of relatively unheralded players. D'Anthony Smith has never played a down in two NFL regular seasons. C.J. Mosley is an eight-year veteran who has started nine games in seven seasons.
