Davis, a teammate of three-star Louisville defensive end commit Lacy Coleman, called the Cardinals Friday and made it official.
"I tried calling them early in the morning but I couldn't get a hold of them. So I called Coach (Kragthorpe) back around 3 (Friday) and I told him I'd like to be a Cardinal," Davis said. "He said 'that's great news and we're glad to have you.' I also talked to Coach (Ken) Delgado and they both were happy to have me as a part of the team."
Davis visited Louisville last month and told InsideTheVille.com earlier this week that he was contemplating making a decision and that the Cardinals were his clear favorite.
"My parents finally realized that Louisville made me happy the most," Davis said. "They were always leaning toward Louisville but they didn't want to pull the trigger too fast. I told them I really didn't think anybody else could matchup with Louisville and they said I could go ahead and (commit). So that's what I did."
Davis caught 42 passes for 810 yards and seven touchdowns as a junior. He projects as a down-field threat because of his 4.3 forty speed and averaged 19.3 yards per catch last season. He also rushed for a touchdown.
With Davis and Coleman both on board, Louisville now will turn its attention to landing a third teammate from Sandy Creek - running back Rajion Neal. Neal plans to decide soon between Mississippi State, Louisville and Kentucky.
"I've known (Lacy) since the seventh grade and he said it's a real blessing that we can go to school together," Davis said. "It would be nice to have Rajion (join us) but I told (him) I can't make his decision for him. I guess he needs a little more time with his decision. I think our decisions to go to Louisville could have a little (influence) on his decision."
Davis said he plans to make an official visit to Louisville this fall but hasn't set up a date yet.
Sandy Creek held their first scrimmage Friday night and Davis caught a couple passes in limited action.
"They took me out kind of early but I caught two catches in the first (two) quarters," said Davis. "Lacy didn't play but he was on the sidelines. I think he tweaked something but it wasn't anything serious."
