CHICAGO -– Outside linebacker Aaron Lynch and tight end Vance McDonald were diagnosed with concussions after leaving Sunday’s game with head injuries.

“I saw both of those guys and they looked fairly well,” 49ers coach Jim Tomsula said.

Lynch and McDonald are in the NFL’s concussion protocol and must pass through the process in order to be cleared for next week's game against the Cleveland Browns.

Linebacker Michael Wilhoite aggravated an ankle injury in the first quarter and did not return to action.

Linebacker NaVorro Bowman returned to action at the start of the second half after testing negative for a concussion. Bowman recorded a game-high 14 tackles.

“I was kind of woozy,” Bowman said, “but I went in and did the concussion protocol. (I) passed all the tests and was able to return.”

--- Wide receiver Torrey Smith said there was a lot of optimism on the sideline on the final play of regulation that Robbie Gould would miss the 36-yard attempt and the 49ers would be going into overtime. But Smith admitted he was not nearly so optimistic.

Smith said he was taking a knee next to Bruce Ellington on the sideline.

“He was like, ‘He’s going to miss it. You want to bet me?’” Smith said.

“He shanked it and I just looked at him, 'Thank you.' He made a great call. A lot of guys knew he was going to miss it. I don’t like wishing bad on anyone, but I’m glad he missed it.”


--- Smith, who had the game-winning 71-yard reception in overtime, became the first 49ers player to register three touchdown receptions of 70 yards or more since John Taylor in 1989. He is the first player in the NFL to reach the mark since Cleveland’s Josh Gordon in 2013.

--- With five receptions for 37 yards, wide receiver Anquan Boldin became the 18th player in NFL history with at least 13,000 yards receiving.

--- Rookie punter Bradley Pinion had a strong day with a 48.1 average on nine punts, including a career-long 62-yarder.

--- It was the 49ers’ first victory in Chicago since their 28-3 win in NFC Championship game in January 1989. The Bears won the past six regular-season games in Chicago against the 49ers. The last regular-season road win against the Bears was a 34-0 victory in November 1974.
