St. Brown recorded six receptions on nine targets for 73 yards in Sunday's 28-24 loss to the Vikings.
St. Brown tied for the team lead in receptions and set up a two-yard touchdown for Jamaal Williams with a 30-yard catch and run midway through the first quarter. He lacked some explosiveness on his catches for the rest of the game, and he told reporters after the game that he rolled his right ankle during the second quarter, per Eric Woodyard of ESPN.com. St. Brown expects to suit up for a Week 4 matchup against the Seahawks, but his status will be worth monitoring throughout the week.
