SEATTLE -- Defensive tackle Justin Smith's ironman streak came to an end Sunday night.
Smith, who started 185 consecutive games since his rookie season of 2001, was declared inactive for the 49ers' game against the Seattle Seahawks due to a left elbow injury.
Smith sustained the undisclosed injury early in the second half of the 49ers' 41-34 victory over the New England Patriots. He was unable to return to action. Smith did not practice last week. The 49ers listed Smith as questionable on their official injury report.
Smith's availability for the final regular-season game next week against the Arizona Cardinals and for the playoffs is not known.
Defensive lineman Ricky Jean Francois will start in place of Smith on Sunday. It'll be the fourth start of Jean Francois' career.
Receiver Mario Manningham returns to the lineup after missing two games with a shoulder injury. Rookie A.J. Jenkins returns to the inactive list with Manningham returning to action. Rookie outside linebacker Cam Johnson will make his NFL debut with veteran Clark Haggans out with a shoulder injury. Johnson will wear No. 50.
For the Seahawks, rookie Jeremy Lane will start at right cornerback for Walter Thurmond, and J.R. Sweezy gets the start at right guard for John Moffitt.

The 49ers signed LB Mark Nzeocha from the Dallas Cowboys practice squad to a one-year deal, the team announced.
In order to make room on the roster, the team has placed DL Tank Carradine on the Injured Reserve List.
Nzeocha (6-3, 240) was originally drafted by the Cowboys in the seventh round (236th overall) of the 2015 NFL Draft. Over the past two seasons (2015-16), he appeared in eight games and registered four tackles. He was waived by the Cowboys on September 3, 2017 and signed to the team’s practice squad on September 5.
A 27-year-old native of Ansbach, Bavaria in Germany, Nzeocha attended the University of Wyoming. He appeared in 39 games (26 starts) and finished his career with 207 tackles, 13 tackles for loss, seven passes defensed, three forced fumbles, two sacks, one fumble recovery and one interception.
Nzeocha will wear number 46.
Carradine (6-4, 270) appeared in each of the team’s first three games this season (two starts), where he registered seven tackles and one sack.

MORRISTOWN, New Jersey — President Donald Trump says his objection to NFL players kneeling during the national anthem to protest police brutality "has nothing to do with race."
Instead, Trump says it has to do with "respect for our country and respect for our flag."
The president made these comments during an impromptu news conference as he boarded Air Force One to return to the nation's capital. Trump says "our soldiers, our first responders" should be treated with respect.
Trump said Friday at a rally in Alabama that NFL owners should fire players who kneel during the anthem.
NFL players and owners around the league condemned his statement, and more than a hundred players sat, knelt or raised their fists in defiance.
But Trump reiterated Sunday NFL owners "should do something" about the protests.
