Crabtree sat out practice Wednesday with a calf injury, but says he will be ready to go in Week 1.
The game in Dallas will be a homecoming for Crabtree, who grew up there and used to sell concessions at the old Cowboys Stadium.
Crabtree played only five regular season games last year after tearing his Achilles tendon over the offseason. He had 203 receiving yards during the playoffs.
Dallas and San Francisco have met three times over the past decade, and the Cowboys have won all three meetings. San Francisco is 14-11-1 against Dallas in regular season play all-time. Including postseason play, the series score is 16-16-1.
