NFL notebook: Falcons lose linebacker Weatherspoon for 8 weeks
• Atlanta has lost linebacker Sean Weatherspoon for at least eight weeks, and running back Steven Jackson will miss the Falcons' next game — and maybe more. Weatherspoon became the third starter placed on injured reserve Tuesday after the team's victory over the Rams, though he will be eligible to rejoin the roster in Week 11. Coach Mike Smith announced Jackson will miss Sunday's game at Miami with a thigh injury. Smith provided no further details on Jackson's injury.
• The Denver Broncos' excitement over their scorching start is tempered by a serious injury to All-Pro left tackle Ryan Clady and the specter of being without Peyton Manning's protector on the blindside for a long period. Clady might miss the rest of the season or at least a good chunk of it with a sprained left foot. The Broncos already have been without two of their other stars. All-Pro linebacker Von Miller is serving a six-game suspension and perennial Pro Bowl cornerback Champ Bailey (foot) hasn't practiced since Aug. 17.
• 49ers nose tackle Ian Williams was placed on injured reserve 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. Williams, a three-year veteran who made his first career start against the Seahawks, has played in six games and has 11 tackles.
• The Colts have 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. Coach Chuck Pagano said Thomas would undergo season-ending surgery. He is expected to be replaced in Indy's lineup by rookie Hugh Thornton, a third-round draft pick.
