Mulder shut down 10-14 days

Left-hander has more shoulder irritation during rehab

SAN DIEGO -- Mark Mulder has experienced another setback in his recovery from left shoulder surgery, and he will not make a scheduled rehabilitation start for Triple-A Memphis on Tuesday.

Mulder made five rehab starts in April and May, and for a time it seemed that he was progressing very well. However, his two Triple-A starts went poorly. After the second game at Memphis, Mulder was shut down again with what the club called a mild rotator cuff strain.

He was sidelined for a week, returning to the mound to throw bullpen sessions on Tuesday, Thursday and Saturday of last week. On the eve of a new rehab assignment, though, Mulder has been pulled back again. The Cardinals describe his current condition as a "lack of range of motion in his left shoulder due to capsular irritation."

According to a release from the team, he is expected to be able to resume his rehab in 10-14 days.

Mulder enjoyed a fine 2005 season for St. Louis, but his '06 campaign was cut short due to a shoulder injury and eventual surgery. He missed nearly all of 2007 as he tried to return from the '06 surgery, then was shut down and had a second operation late in the year.
