Syndergaard (elbow) is expected to begin a rehab assignment this week, Tim Healey of Newsday reports.
Syndergaard threw a pair of live batting practice sessions recently, and he'll take another step by returning to game action this week. The Mets haven't yet announced where the right-hander will begin his rehab assignment or when he'll make his first appearance, but he shouldn't require much time to build up his workload since he's expected to serve as a reliever once he's activated.
