Vikings DE Brian Robison (shoulder) is officially questionable, but expects to play in Sunday's season finale against the Packers. "I'm sure Sunday it's going to be painful," Robison said on Friday. "But bottom line is we're trying to clinch a playoff spot and we need all hands on deck." Robison suffered a Grade 3 sprain of the AC joint in his right shoulder on Dec. 16 at St. Louis and sat out last weekend's win at Houston, which set up Sunday's win-and-in situation against the Packers at the Metrodome. Coach Leslie Frazier said he'd ultimately lean on Robison to make the decision.
