The San Francisco 49ers have ruled out George Kittle with a hamstring injury, early in Sunday's game against the Seattle Seahawks.

Kittle went to the blue medical tent in the second quarter of the game. He emerged and was seen on the sideline in a baseball cap, signaling the end of his day.

The team announced the news shortly before halftime, confirming that Kittle would not return to the game. It is unclear whether the team believes that the injury will keep Kittle out longer-term.

Prior to getting injured, Kittle went four-for-four on catches for 25 total yards, including a five-yard touchdown catch that gave the 49ers a 7-0 lead.

Seattle went on to score a touchdown of its own on the next drive to tie the game at 7-7.
