Blue Jays right-hander Brandon Morrow had to be helped off the field after he was struck on the lower right leg by Wilson Betemit's line drive in the seventh inning of Wednesday night's game against Baltimore.
X-rays were negative, and Morrow was diagnosed with a bruised right shin. He is day to day.
Morrow was hit between the knee and ankle on Betemit's infield single and hopped around the mound in obvious pain.
Manager John Farrell and a Blue Jays trainer came to the mound to check on Morrow and, following a brief discussion, supported him on either side as he limped off the field and into the dugout, disappearing down the steps to the clubhouse.
Carlos Villanueva came on to replace Morrow, who allowed one run and four hits in 6 1-3 innings.
