The Chicago Cubs are expected to place starter Matt Garza on the 15-day disabled list, The Chicago Tribune's Paul Sullivan reported on Twitter.
Sullivan later added in a report that Garza had been sent back to Chicago after feeling stiffness in his arm during a bullpen session. Garza has not pitched since July 21, when he left a start in St. Louis after his triceps cramped up.
"He's stiff today," manager Dale Sveum told Sullivan. "Nothing major, but he's not going to be able to go on Tuesday. He threw two sides ... Just back him off, just send him home to go see the doctor. Just being a little (cautious)."
Garza is 5-7 with a 3.91 ERA this season. He has 96 strikeouts in 103 2/3 innings.
He was the subject of much trade speculation leading up to last week's deadline. The Reds, Rangers, Dodgers and even Red Sox were all reportedly interested
in acquiring Garza.
