Source: Bucs OT Demar Dotson treated for knee sprain after MRI

Tampa Bay Buccaneers right tackle Demar Dotson underwent an MRI on Sunday morning to determine the severity of the knee injury he sustained in Saturday night's preseason opener against the Minnesota Vikings.

The MRI showed that Dotson's ligament is intact and it's being treated as a knee sprain, a source tells

Dotson, who is widely considered to be the Buccaneers' best lineman, suffered the injury in the second quarter in the 22-11 loss.

The Buccaneers' offensive line appeared woeful in the opener as rookie quarterback Jameis Winston was sacked twice and hurried quite often. Winston completed 9 of 19 balls for 131 yards and an interception.

Tampa Bay is banking on two rookie linemen --€“ former Penn State offensive tackle Donovan Smith and former Hobart offensive guard Ali Marpet --€“ to protect their young passer.

Dotson, who is set to make $2.5 million in base salary this season, staged a brief holdout before the first set of mandatory workouts in June. Dotson, though, stopped his holdout as he wasn't willing to deal with the fines that come with missing mandatory practices.

The Bucs acquired Dotson in a trade with the Bears for former first-round pick Gabe Carimi in 2013
