(CBS) White Sox catching prospect Josh Phegley won’t start the Arizona Fall League season on time for the second straight year, the Chicago Tribune reports.

Phegley was scheduled to have his sore left wrist examined Wednesday, one day after the AFL begins play. Phegley could rejoin his Mesa Solar Sox teammates later this fall if cleared by the White Sox medical staff.

The 23-year-old catcher batted a combined .242 with nine home runs and 56 RBIs in 116 games with Double-A Birmingham and Triple-A Charlotte. He missed the entire AFL season in 2010 because of a low blood platelet count that eventually caused his spleen to be removed.

Filling in for Phegley on the AFL roster will be Michael Blanke. The 22-year-old batted .246 wth nine home runs and 43 RBIs in 115 games with Class-A Kannapolis and Class-A Winston Salem.
