White Sox starter Jake Peavy had his minor league rehab assignment halted last week due to muscle tenderness and irritation in his right shoulder.
That rehab is going to start up again shortly.
From MLB.com beat writer Scott Merkin comes word that Peavy threw 40 pitches off a mound Sunday with the intensity of a regular start.
He reported no issues with his shoulder and could be cleared to resume pitching in minor league games as soon as Friday as long as his next couple throwing sessions go as smoothly.
The White Sox will likely ask Peavy to make multiple appearances at their minor league affiliates before activating him from the disabled list and trusting him to start a big league game. He has not taken a mound in the major leagues since July of 2010.
