Canha banged his left hand against the wall in Wednesday's win over the Giants. The injury is not considered serious, and the A's outfielder will likely be back in the lineup Friday.
Meanwhile, Khris Davis returns to the Oakland lineup as the designated hitter after pinch-hitting in each of the last two games in San Francisco. He will bat fifth. Corban Joseph will make his second straight start at second base and hit seventh.
The A's will turn to their ace on the mound, veteran right-hander Mike Fiers. The 34-year-old has won nine straight decisions, allowing three runs or fewer in each of his last 19 outings.
For the season, Fiers is 11-3 with a 3.30 ERA and 1.11 WHIP in 25 starts. However, the former Astro is just 1-2 with a 5.29 ERA in six career starts against his old team.
Houston will counter with 27-year-old Aaron Sanchez. The right-hander struggled in 23 starts with the Blue Jays this season, going just 3-14 with a 6.07 ERA. But since joining the Astros, Sanchez is 2-0 with a 0.82 ERA. In six career games against Oakland, he is 1-2 with a 5.12 ERA.
