(Eugene, OR)  --  Oregon running back Thomas Tyner's dad is clearing up things for his son.  John Tyner tells the "Oregonian" Thomas underwent shoulder surgery, but does not plan on transferring from the school.  The elder Tyner says " Thomas is a Duck, he's going to be a Duck."  The younger Tyner has a redshirt season available to him and will have two years of eligibility remaining should he sit out this season.
