The win against St. Louis Sunday is proving to be costly.
Weatherspoon became the third starter placed on injured reserve Tuesday after the victory over the Rams, though he will be eligible to rejoin the roster in Week 11.
The Falcons (1-1) used the one-time-only designation that allows an injured player to return, but Weatherspoon won’t be able to practice for six weeks and can’t play in a game for eight weeks.
Coach Mike Smith announced Jackson will miss Sunday’s game at Miami with a thigh injury.
Smith said Jackson’s injury is not expected to keep him out for a significant amount of time.
“He will not play this week. I know that,” Smith said. “It is short term. When I say short term, I don’t know if it’s two weeks or three weeks, but Steven is ruled out for the game this week and will not play.”
Smith says Jacquizz Rodgers and Jason Snelling will share the work at running back against the Dolphins.
The announcements came a day after the Falcons placed defensive end Kroy Biermann (torn right Achilles tendon) and fullback Bradie Ewing (separated left shoulder) on the reserve list with season-ending injuries.
The Falcons signed linebackers Jamar Chaney and Omar Gaither on Tuesday.
Smith said two undrafted rookies, Joplo Bartu and Paul Worrilow, will now play significant roles for the Falcons’ defense.
The status of cornerback Asante Samuel also is in doubt. Samuel left the game against the Rams with a thigh injury.
LIONS: Made a big investment in quarterback Matthew Stafford during the off-season and, so far, he’s earning it.
The fifth-year veteran has 635 passing yards and four touchdowns two games into the season. The former Georgia star signed an extension that will pay him $41.5 million in guaranteed money and as much as $76.5 million total.
He’ll get a chance to add to his hot start Sunday when the Lions travel to Washington, which has seen opposing signal-callers complete 73 percent of their passes with six touchdowns in the new season.
“I’m just trying to play smart. I’ve had another year of experience,” Stafford said.
49ERS: Nose tackle Ian Williams was placed on injured reserve Tuesday with a broken left ankle.
Williams, who was scheduled to undergo surgery on the ankle, was injured on by a block by J.R. Sweezy early in the 49ers’ 29-3 loss to the Seattle Seahawks on Sunday.
JAGUARS: Joined an Orlando television station that felt the need to explain for having to air Jacksonville’s road game at Oakland last weekend to get two fans to London for the team’s Oct. 27 game against San Francisco.
The Jaguars insist the promotion has been in the works for some time and is not a response to what happened Sunday.
Team President Mark Lamping says Orlando is a key region because “nowhere is our effort to raise the Jaguars’ following and profile more evident or important than in central Florida.”
The CBS affiliate, WKMG TV, issued an on-air explanation for why it was showing the Jaguars while many viewers probably preferred seeing the Broncos-Giants game.
SUPER BOWL: Fans can prepare to pay double for the best seats.
The NFL expects the most expensive tickets for its championship game will be about $2,600 each for 9,000 premium seats for the Feb. 2 game at MetLife Stadium in East Rutherford, N.J.
That’s more than twice the $1,250 cost for similar tickets at last season’s Super Bowl in New Orleans.
PANTHERS: Signed safety Robert Lester from the practice squad and placed veteran safety Charles Godfrey on injured reserve with a torn Achilles tendon.
COLTS: Placed left guard Donald Thomas on injured reserve and waived fullback Dan Moore.
Thomas tore a quad tendon in his right leg during the first quarter of Sunday’s 24-20 loss to Miami.
