Sam Bradford required an MRI on his twice surgically repaired knee Tuesday after experiencing swelling, pain, and discomfort. The test came back negative, sources told ESPN's Chris Mortensen.
While the Minnesota Vikings are concerned about the injury, they're "cautiously optimistic" about their starting quarterback's status for Week 2, added Mortensen.
Head coach Mike Zimmer confirmed Bradford's status Friday, saying he anticipates he'll play against the Pittsburgh Steelers, according to ESPN's Adam Schefter.
Bradford has been listed as limited for the past two days of practice.
The former No. 1 overall pick has twice torn his left ACL.
Bradford lit up the New Orleans Saints on Monday night, throwing for 346 yards with three touchdowns in a 29-19 win.
