San Francisco 49ers tight end George Kittle was optimistic about his chances of playing in Week 7 against the Atlanta Falcons after missing the last five games with a hamstring injury. Here's what we know about his status.

Niners tight end George Kittle was placed on injured reserve Tuesday after he left Sunday’s 17-13 win over the Seattle Seahawks with a hamstring injury, according to ESPN's Adam Schefter. Reports Monday suggested the injury would sideline Kittle for multiple weeks.

The San Francisco 49ers released their latest injury updates headed into the Week 7 contest versus the Atlanta Falcons.

Fantasy Impact: Dawson Knox played 81% of the team's offensive snaps and scored a touchdown on his only reception. The Bills are on their bye in Week 7, likely giving Kincaid the required time to return to the lineup in Week 8 against the Panthers.

Kittle pulled up during the second quarter and retired to the locker room for assessment. He didn’t return to the game. Tests confirmed the worst news - a Grade II hamstring strain, which would keep him out for between three to five weeks.
