David Wright’s back might be improving, but he still hasn’t been officially cleared for baseball activities.

The Mets third baseman, who is rehabbing from spinal stenosis and has not played since April 14, was scheduled Monday to have his weekly checkup with Dr. Robert Watkins in Los Angeles, and according to general manager Sandy Alderson there has been “no change” in Wright’s status.

A day earlier, manager Terry Collins indicated Wright was “on the upswing” and “doing some things that are related to baseball activities.”

Wright, who has played only eight games this season, will soon be up against the clock in his hopes for a 2015 return.

Once Wright is cleared for baseball activities, he will likely need at least three weeks before his return to major league action, and that is provided he doesn’t incur a setback during that time frame.

Alderson has indicated he expects Wright to play again this season, but that expectation won’t preclude the GM from making a potential deal to bolster the lineup.

Daniel Murphy has settled in at third base in Wright’s absence with Wilmer Flores at second and Ruben Tejada at shortstop.

Last week in Los Angeles, in a visit with teammates at Dodger Stadium, the Mets captain said he has “one shot” to get his back right and he isn’t going to rush the process. Wright also added that he expects to play again in 2015.
