Ace will be re-evaluated after two weeks
Halladay, last season's AL Cy Young Award winner, has a tired right shoulder that won't improve without rest. He is 7-7 with a 4.35 ERA this season.
He will be re-evaluated after two weeks of rehabilitation, probably at the Blue Jays' spring training complex in Dunedin, Fla.
"In layman's terms, he's got a fatigued shoulder," general manager J.P. Ricciardi said. "No tears. Nothing surgically that needs to be done. The MRI results were negative."
Catalanotto went on the disabled list June 26 with a right groin injury. He's hitting .327 with one homer and 23 RBIs this season.
The Blue Jays also signed left-hander Zachary Jackson, their first-round draft pick. Jackson went 10-7 with a 3.58 ERA for Texas A&M this season. He is expected to report to Class-A Auburn of the New York-Penn League on Wednesday.
