OKLAHOMA CITY - ESPN's Joe Schad reported Sunday morning that Oklahoma safety Tony Jefferson and receiver Kenny Stills will forgo their final season of eligibility at OU and enter the 2013 NFL Draft.

Coming off a disappointing 41-13 loss against Texas A&M in the Cotton Bowl, this potentially comes as more bad news for Sooner fans.

Stills led the Sooners in receiving this past season with 82 receptions for 959 yards and 11 touchdowns.

Jefferson led the team with 119 tackles (85 solo) and also had 3.5 tackles for loss and two interceptions.

Jefferson earned first team All-Big 12 honors this season, while Stills landed on the second team. Both California natives are regarded as second-to-third round draft prospects.

There has yet to be a formal announcement from either player, but Jefferson said on Twitter on Saturday that he had yet to make up his mind.

Via Twitter: "Smh guys I promise I will let you guys know when I decide. But as of now. I'm nowhere near deciding .."
