Jay traveled to the Cardinals' Jupiter, Fla., complex earlier this week, hopeful of first increasing his workouts and then taking the field in either extended spring training or Minor League rehab games. That timeline has been pushed back as Jay and the club await the results of Thursday's examination.
"He's still feeling a little something," manager Mike Matheny said. "But with everything that we're seeing, he should be further along. We're going to get one more look at it, and after that, we're probably going to push through."
Jay has been on the disabled list since May 16; however, the shoulder ailment has been bothering him for much longer. Jay first injured it on April 19, when he ran into the center-field wall while trying to make a catch. He missed the next six games before returning and playing through some discomfort. When that discomfort became debilitating to his swing, Jay was moved to the DL.
At the time, the expectation was that Jay would only need to miss the minimum 15 days. That's not the case, as Jay would be eligible to come off the DL on Thursday.
"It's gotten almost worse," Matheny said. "It will be nice to get another look at it and see what comes of that. That will give him a little peace of mind, too. Some guys are just hesitant to push through something."
