San Francisco quarterback Brock Purdy was a limited participant in practice Wednesday and has a chance to play on Sunday, 49ers coach Kyle Shananah said.

Toe and shoulder injuries kept Purdy on the sideline for San Francisco’s 26-21 win at New Orleans last week. He has a form of turf toe and was expected to miss multiple weeks. In a spot start, backup Mac Jones completed 26 of 39 passes for 279 yards and three touchdowns without an interception.

The 49ers (2-0) play their home opener on Sunday against the Arizona Cardinals (2-0).

Purdy, 25, is nursing left shoulder and toe ailments after completing 26 of 35 passes for 277 yards, two TDs and two interceptions in the season-opening 17-13 victory at the Seattle Seahawks.
