Jose Reyes is going on the Disabled List after sustaining a hamstring injury during a game against the Yankees last weekend. The Mets announced the shortstop’s roster move on Twitter:

The injury comes at a crucial time for both player and team. With Reyes in the midst of an MVP season , and in the last year of his contract, the Mets must decide whether to try and sign the shortstop to a new contract or to trade him for other assets. While the Mets are three games over .500, they are also seven games back of the wild-card leading Atlanta Braves.

For Reyes, this most certainly means that he will be unable to play in this year’s All-Star game that he was recently voted to start in. It also might impact his future contract.

This is not the first time Reyes has gone on the DL. In 2009, he appeared in only 36 games as he dealt with nagging hamstring injuries. In 2004, he played in only 53 games after fracturing a fibula. If this latest injury drags on, teams might be reluctant to sign him for fear or future injuries.

The Mets shortstop is expected to miss three weeks of action, according to ESPN’s Enrique Rojas. So if you’re looking for a replacement in your fantasy leagues, you may be able to get by with a stopgap solution. That could mean taking the steady, but unspectacular production of Miguel Tejada, the streaky but limited speedster Emilio Bonifacio, or taking a chance on recently returned Japanese import Tsuyoshi Nishioka.
