ARLINGTON, Texas — After tweaking a knee in practice earlier this week, Oklahoma State tackle Russell Okung is expected to play against Ole Miss in the 74th Cotton Bowl Classic at 1 p.m. Saturday at Cowboys Stadium. Okung’s streak of 46 straight starts appeared to be in jeopardy Wednesday. Sources close to the program said the consensus All-American tackle "tweaked” a knee during Tuesday’s practice at Cowboys Stadium, resulting in all precautions taken for a player expected to be a first-round pick in the 2010 NFL Draft. But Okung, the Big 12 Offensive Lineman of the Year, was suited up at Oklahoma State’s practice Wednesday. And a source said that he is expected to go against Ole Miss, extending a consecutive starts streak that dates back to his freshman season. The Rebels feature an athletic and aggressive defensive line, including end Greg Hardy, who himself is returning from a broken wrist. Hardy joins junior Kentrell Lockett to provide Ole Miss with dual defensive ends equally adapt to test Okung’s ability to move like normal. The loss of Okung would have been yet another blow for a team that has been hit hard by injuries this season. OSU’s top lineman, Okung is the No. 1 offensive line prospect for the draft by ESPN analysts Mel Kiper Jr. and Scouts Inc. Both have Okung slotted at No. 6 on their talent boards. ESPN’s Todd McShay projects Okung going to the Kansas City Chiefs at No. 5 overall. Since the injury appears to be minor Okung’s draft stock is unlikely to be effected. Okung has been one constant through four years of solid offenses — and a school-record four straight bowl bids — recently providing blind-side protection and comfort for quarterback Zac Robinson. The lone offensive player listed among 12 semifinalists for the Lombardi Award, Okung allowed just one sack in 836 snaps this season. If Okung is limited by the knee injury, the Cowboys could move senior Brady Bond from right tackle to the left side, with Andrew Mitchell stepping in. Bond is slated to see his first action since spraining an ankle in mid-November, but, thanks to a strong showing in December practices by Mitchell, it remains unclear who will start at right tackle if Okung continues his string of starts at left tackle.
