NORMAN, Okla. (AP) -Oklahoma linebacker Curtis Lofton will skip his senior season and enter the NFL draft.

Lofton, the Sooners' leading tackler last season, is the team's second junior to declare for the draft this year, joining receiver Malcolm Kelly.

``Curtis made a lot of big plays during his time here,'' OU coach Bob Stoops said Monday. ``We wish him all the best in the NFL.''

Lofton, a second-team All-American, said he reached the decision Sunday.

``I'll definitely miss my coaches and teammates,'' he said. ``I came in with my class three years ago and those guys are like brothers to me. And I'll miss playing in front of those 85,000 fans.

Lofton had 157 tackles in 2007, sixth-best total in school history.

He also established a school record with nine double-digit tackle games, and had a career-high 18 tackles in the first meeting with Missouri this season.
