Minnesota Vikings left end Brian Robison is in danger of missing Minnesota's pivotal Week 16 game against the Houston Texans. According to ESPN1500, Robison is dealing with a Grade 3 strain of the AC joint in his right shoulder.
Robison, predictably, did not participate in Minnesota's practice on Wednesday, as the Vikings prepare to take on one of the NFL's top teams.
Despite the injury, Vikings head coach Leslie Frazier is hoping that Robison will be able to play on Sunday.
"We're hoping that he'll make it," Frazier said. "But it'll be day to day. We probably won't know anything until probably Friday, just to see whether he's making continued progress throughout the week."
Through Minnesota's first 14 games, Robison has recorded seven and a half sacks while registering 36 tackles. Robison has also forced two fumbles and has one fumble recovery.
If Robison is unable to play, the Vikings would likely start either Everson Griffen or D'Aundre Reed. Griffen replaced Robison during Minnesota's Week 15 win over St. Louis, but Reed is listed behind Robison on Minnesota's depth chart.
More will be known regarding Robison's availability as the week progresses.
