Toronto Blue Jays ace R.A. Dickey leaves game with neck and back stiffness

TORONTO - Toronto Blue Jays ace R.A. Dickey exited Thursday's game against the Chicago White Sox after the sixth inning with neck and back tightness.

Dickey gave up two hits over six innings while striking out seven and walking one before leaving the game.

With two outs in the fifth and Toronto leading 3-0, the knuckleballer had trainer George Poulis and John Gibbons come to the mound for a talk. He finished the inning by getting White Sox infielder Jeff Keppinger to fly out.

Blue Jays reliever Esmil Rogers came in to pitch the seventh inning.
