Ten miles from the Grand Ole Opry, Christian Ponder wants to put on a show of his own Thursday night in Tennessee. But he insists he doesn't consider it an audition. Ponder, the Vikings' third-string quarterback after being the primary starter the previous three seasons, expects to play a "significant" amount in the preseason finale against the Titans in Nashville, Tenn. "I just want to go out and have a good game, not for an audition for another team or anything, but for myself and this team," Ponder said Tuesday. "Right now, my thoughts are securing a spot on this roster." Ponder has dropped behind starter Matt Cassel and rookie Teddy Bridgewater on the depth chart. Still, it seems unlikely that Ponder, who is being paid a guaranteed $1. 76 million this season, would be released by Saturday's deadline to get down to 53 players. With St. Louis, Minnesota's opponent in the Sept. 7 regular-season opener, already having lost starting quarterback Sam Bradford for the season, Ponder was asked if he's keeping an eye out for possible openings on other teams. He reiterated that he's not asking for a trade.
