TULSA, Okla. (AP) -Running back Courtney Tennial will miss Tulsa's entire 2007 season because of an ankle injury sustained in preseason drills.

The transfer from Oklahoma was the Golden Hurricane's leading rusher last season with 862 yards and 14 touchdowns.

Tennial has played only one season of college football, but the school said Wednesday he will have to seek a waiver for a sixth year of eligibility from the NCAA if he is to continue his career.

After setting an Oklahoma high school record with 3,486 yards rushing and 36 touchdowns as a senior at Glenpool High School, Tennial redshirted at Oklahoma in 2003 and didn't play the following year as Adrian Peterson was en route to a runner-up finish in the Heisman Trophy voting.

He then transferred to Tulsa and sat out a season under NCAA rules before playing last season.
