Lonergan is one of 51 players named to the watch list for the Rimington Trophy, which is annually presented to college football's top center.
Clement was named to the preseason watch list for the John Mackey Award, presented annually to the nation's top tight end.
A New Orleans native, Lonergan headlines a list of 10 SEC players on the Rimington list. The last Tiger player to win the award was Ben Wilkerson in 2004.
When the 2012 season gets started, Lonergan will become the first LSU center to start at least one game at the position in four seasons since Wilkerson did so from 2001-04.
As a junior, Lonergan saw action on 677 snaps and recorded 65.5 knockdown blocks. He has started 26 career games and LSU owns a 22-4 record in those contests.
A native of Thibodaux, Clement is a two-year starter with 9 career catches for 138 yards and one touchdown that came on a 1-yard strike from Jarrett Lee last season at West Virginia.
Clement is one of the most experienced offensive players for LSU with appearances in 40 games. He has also seen extensive playing time on special teams because of his athleticism and outstanding blocking ability. He is one of seven candidates from the SEC on the 33-player watch list, and he is the first Tiger named to the Mackey watch list since Richard Dickson was selected in 2008 and 2009.
