TORONTO -- Blue Jays shortstop Yunel Escobar continues to take positive steps in his recovery from a mild concussion.
Escobar traveled with Toronto on its West Coast trip to Anaheim late Thursday night. He went through a series of physical and mental tests the following day without experiencing any negative symptoms.
As per league policy on concussions, Escobar must go through those tests again on Saturday to ensure there are no lingering effects. If all goes well, he could play as early as Sunday.
"It's a matter of reproducing it day after day so there is no reoccurence or those symptoms reemerging," Blue Jays manager John Farrell said.
Escobar suffered the injury on a collision with Oakland third baseman Andy LaRoche on Wednesday night.
At the time of the incident, Escobar had been one of the most productive hitters in the Blue Jays' lineup. He was batting .474 with one home run and three RBIs.
