IRVING, Texas (AP) -- Landry Jones is back where he made his Oklahoma debut, and again in the shadow of a Heisman Trophy winner.

Jones took over as the Sooners quarterback in the first-ever college game at Cowboys Stadium, in the 2009 season opener when he replaced injured Heisman winner Sam Bradford after halftime.

Three seasons later in the same stadium, Jones makes his 50th and last career start. The 12th-ranked Sooners play the Cotton Bowl on Friday night against 10th-ranked Texas A&M and dual-threat quarterback Johnny Manziel, the first freshman to win the Heisman.

Along with a matchup of 10-2 teams and former Big 12 rivals, the Cotton Bowl pits the steady veteran with 39 wins and 16,368 yards passing and exciting 20-year-old freshman with 4,600 total yards in 12 games.
