HUNTSVILLE, Alabama -- Grissom head football coach Dale Overton has resigned following the second winless season in program history.



Overton's resignation was first reported by AL.com's news partner, WHNT News 19. Overton told the news station that he had other, "potential opportunities". Efforts by AL.com to reach Overton this afternoon were unsuccessful.



Overton led Grissom for two seasons. The Tigers finished 0-10 in 2013, the program's first winless season since 1990. Grissom entered the year after having lost several key players - including All-State performer Thomas Hill - to graduation following a 3-7 showing in 2012.



Injuries compounded the difficulty for Grissom. Standout receiver/defensive back E.J. Turner and starting quarterback Easton Brock got hurt early in the season. The low point came in a 47-0 loss to archrival Huntsville in Week 2, the largest margin of victory in series history, as Turner and Brock saw limited action.



Grissom set program marks for least points in a season (57) and most points allowed (441). The Tigers last made the playoffs in 2004, haven't enjoyed a winning season since 2002, and haven't won a postseason game since 2000.



Overton came to Grissom from Prattville, where he was the offensive coordinator for the Lions' 2011 Class 6A state championship team. Overton became Grissom's fifth coach in five seasons, following Bobby Rhoades (2009), Keith Henderson (2010) and Joe Dasaro/Matt Clouser (2011).



Overton had previous stints at Tharptown (head coach from 2006-08), Auburn High (offensive coordinator 2000-05), Chilton County (head coach 1999) and Central-Phenix City (assistant 1993-99). He was a first-team All-State wide receiver at Hackleburg in 1986, and he went on to be a four-year letterman at Auburn.



Grssom becomes the third school in the Huntsville region to lose a coach since the end of the season. North Jackson fired Tony Johnson, and Tim Gillespie resigned from Sparkman.
