SANTA CLARA \u2013 Quarterback Brock Purdy is \u201chighly unlikely\u201d to start on Sunday for the San Francisco 49ers as he deals with a toe injury that has already sidelined him for one game.<\/p>\n
Purdy was officially listed as questionable for the game against the Arizona Cardinals with a final decision on his status likely to come on Saturday. Coach Kyle Shanahan said Purdy could be available as the backup or the emergency third quarterback if he can\u2019t start.<\/p>\n
\u201cA lot of progress and thought he had a good week,\u201d Shanahan said. \u201cWe\u2019ll see how he does tomorrow. It\u2019s highly unlikely that he will start.\u201d<\/p>\n
Mac Jones would start his second game for San Francisco if Purdy isn\u2019t ready. Jones threw for 279 yards and three TDs in his first start last week against New Orleans.<\/p>\n
If Purdy is inactive or designated as the emergency third quarterback, San Francisco would have to elevate Adrian Martinez from the practice squad on Saturday to be available for the game.<\/p>\n
Purdy hurt his toe in the season opener at Seattle and missed last week\u2019s win at New Orleans with the injury. He returned to practice this week<\/a> on a limited basis.<\/p>\n Purdy initially hurt the toe in the first half against the Seahawks, but was able to play through the injury on adrenaline. Purdy went 26 for 35 for 277 yards with two TDs and two interceptions and led a game-winning TD drive capped by a 4-yard pass to Jake Tonges<\/a>.<\/p>\n
