When the Sooners trot out onto the field for the first time at newly expanded Oklahoma Memorial Stadium, the stadium may be updated, but what fans will see on the field will be classic Oklahoma.

To welcome an extra 8,100 fans into the stadium, expanded to include an additional 2,500 club seats and 27 new luxury suites, Sooners players will will be wearing retro crimson and cream jerseys reminiscent of those worn during the Bud Wilkinson coaching era (1947-1963), a time period when the Sooners had a 47-game winning streak and captured three national championships. Bob Stoops and his coaching staff will be outfitted in gear similar to that worn during the Barry Switzer coaching era (1974-1989), when the school's football team won another three national championships.

A record crowd of 81,000 is expected for the Sooners' season opener Aug. 30 against North Texas.

"Our renovation and expansion has given our fans all the up-to-date amenities, but we also wanted to do something fun to remember our roots and tradition," athletic director Joe Castiglione said. "It provides a link from our foundation to the position the program is in today."

Replica jerseys and sideline apparel made by Nike will be called "The Legacy Series" and will be available for Sooners fans to purchase in the fall. Jerseys will be available with the numbers of current day players as well as Nos. 35 and 36, which belong to 1952 Heisman Trophy winner Billy Vessels and 1969 Heisman Trophy winner Steve Owens, respectively.

The actual jerseys worn by the players during the game also will go up for auction with part of the proceeds going to the University of Oklahoma Student Athlete Scholarship Fund and another portion earmarked for a scholarship endowment for post-eligibility student-athletes to assist them in finishing their degrees, Castiglione said.
