Biggsy is also running with it. http://espn.go.com/chicago/nfl/story/_/id/9940507/jay-cutler-chicago-bears-practices-first-injury LAKE FOREST, Ill. -- Chicago Bears quarterback Jay Cutler has been cleared to play and is expected to start Sunday against the Detroit Lions, coach Marc Trestman said Thursday. Cutler returned to the practice field Thursday, about 2½ weeks after tearing a groin muscle during an Oct. 20 game against the Washington Redskins. The original diagnosis was for him to miss four weeks. "Jay has spent, since the day he got hurt, really 24/7 doing everything he can on and off the field to get ready," Trestman said. No. 2 quarterback Josh McCown has had great success in relief of Cutler, but Trestman said Cutler "took every rep" in practice and expects him to be able to start. "Jay is unique regarding he really understands his body," Trestman said. "He understands how to take care of himself, and he's a unique athlete. There was an incredible amount of hard work and effort that he had put in to even have a chance. We're excited about it. It says a lot about his commitment to the team. He came in this morning, did a few of the things. The doctors said, 'You're good to go.' " ESPN.com Bears reporter Michael C. Wright contributed to this report.
