SANTA CLARA, Calif. -- After missing Sunday's victory against the New Orleans Saints because of a toe injury, San Francisco 49ers quarterback Brock Purdy could return this week against the Arizona Cardinals .

Last week at this time, Niners coach Kyle Shanahan called Purdy a "long shot" to play against the Saints, all but ruling him out five days before that game. But Shanahan struck a different, more positive tone Wednesday when he said Purdy will be a limited participant in practice and was asked whether Purdy could be under center for the home opener on Sunday.

"He wasn't limited last week," Shanahan said. "He does have a chance [to play]."

Purdy did some throwing during individual drills during the early open portion of practice open to media.
