49ers reportedly placing Kittle on IR; Purdy uncertain for Week 2

The San Francisco 49ers' injury woes continue.

Head coach Kyle Shanahan announced Monday that quarterback Brock Purdy is uncertain for Sunday's game against the New Orleans Saints due to injuries to his left shoulder and toe, according to ESPN's Adam Schefter.

San Francisco is also placing tight end George Kittle on the injured reserve, which will sideline him for at least four games due to a hamstring injury, sources told Schefter. He could miss up to five weeks, according to NFL Network's Ian Rapoport.

Purdy's toe injury is a bigger concern, Shanahan noted.

"We're not sure. We'll see how it heals and how the week goes," the sideline boss said about his quarterback, according to The Associated Press' Josh Dubow.

Shanahan also announced that receiver Jauan Jennings' shoulder MRI came back clean. The team is still evaluating his status for Week 2.

Kittle and Jennings were unable to finish Sunday's 17-13 win over the Seattle Seahawks. Purdy played the entire game, completing 26 of 35 pass attempts for 277 yards and two touchdowns against two interceptions. San Francisco will turn to Mac Jones under center if Purdy misses time.

The Niners reunited with Kendrick Bourne on Monday, signing the veteran wideout to a one-year contract. The club is already missing its top wide receiver, Brandon Aiyuk, who's still recovering from a torn ACL.

Shanahan also had an injury scare with running back Christian McCaffrey, who was a surprise addition to the injury report last week due to a calf issue. However, McCaffrey played versus the Seahawks, leading the team with 31 touches.

Tight ends Jake Tonges and Luke Farrell will presumably have an increased workload with Kittle sidelined. Tonges caught his first career touchdown against Seattle.
