Mets manager Terry Collins admitted Friday that there's a chance David Wright (hamstring) might not play again this season. Wright was originally expected to miss only 3-5 weeks, but is dealing with a fairly significant injury and remains without a timetable to resume baseball activities. "No question," Collins said. "There's nothing etched in stone. If he gets back, tremendous. That means the healing process and all the rehab stuff will work. But there is absolutely no timetable at all."
