Robison ruled out with shoulder injury
ST. LOUIS (AP)
The team said early in the second half he would not return.
Robison has 7 1/2 sacks after dropping Sam Bradford for an 8-yard loss on the Rams opening possession.
It was not clear how Robison was hurt during a 15-yard carry by Steven Jackson. He left the field favoring his right side.
Everson Griffen, who replaced Robison, had a 29-yard interception return for a touchdown in the Vikings' 23-point second quarter.
