49ers' Mac Jones to start for injured Brock Purdy; George Kittle back - ESPN

SANTA CLARA, Calif. — The San Francisco 49ers will welcome tight end George Kittle back from his hamstring injury Sunday night against the Atlanta Falcons, but quarterback Brock Purdy's return from a toe ailment will have to wait at least another week.

Niners coach Kyle Shanahan ruled Purdy out Friday with receiver Ricky Pearsall (knee), linebacker Fred Warner (ankle) and defensive lineman Yetur Gross-Matos (hamstring) also unavailable against the Falcons.

Jones has largely fared well in Purdy's stead, averaging what would be a league-high 313 passing yards per game in his four starts to go with six touchdowns and three interceptions for a QBR of 53.0.

While Purdy has worked his way back from the toe injury, Jones also has been dealing with health issues. He was questionable last week with knee and oblique soreness, but he was a full participant in practice Thursday and Friday and is set to go against Atlanta.
