Baltimore Ravens quarterback Joe Flacco will wear a brace on his left knee in Sunday's game against the New England Patriots. On Monday night, Flacco was hit by the helmet of Detroit Lions linebacker DeAndre Levy, who had dived at the reigning Super Bowl MVP midway through the fourth quarter of Baltimore's 18-16 win. An MRI revealed a mild MCL sprain, a league source told ESPN NFL Insider Adam Schefter. Flacco didn't have a noticeable limp when walking to the practice field and to the locker room. He wore the brace in Wednesday's practice and will wear it against the Patriots, whether the trainers recommend it or not. Source: ESPN
