Sources tell TSN that Mats Sundin had an MRI on Monday to update the status of a slight ligament tear in his right elbow suffered two weeks ago. The test results showed the healing process is on, or slightly ahead of schedule, which means Sundin could be ready to return on Saturday versus the Boston Bruins. However, Toronto will not rush Sundin back, so if he feels any level of discomfort in his rehab this week, his return will be pushed back.
