It was a tough break for Mississauga’s Brent Urban today who had to be carted off the field after suffering what’s believed to be a knee injury at the Baltimore Ravens’ training camp. Urban, 23, played his high school football with the Lorne Park Spartans before heading down to the United States to play for the University of Virginia Cavaliers. In May, he signed a four-year contract with the Ravens for $2.52 million.
