Houston Texans defensive end Antonio Smith was suspended by the NFL on Wednesday for the season opener and the last two exhibition games for hitting Miami guard Richie Incognito with the Dolphins player's helmet.
Smith ripped the helmet off Incognito's head, then hit Incognito on the shoulder with it in Saturday night's exhibition game.
Smith must sit out Houston's visit to San Diego to begin the season Sept. 9. He also will lose about $400,000 in salary for his seventh rules violation since 2011.
Texans running back Arian Foster was removed from the physically unable to perform list and practiced for the first time since May.
Foster strained his right calf in an off-season practice in late May and struggled with a sore back after recovering from that injury.
Foster rushed for 1,424 yards and 15 touchdowns last year for his third straight 1,200-yard season.
A person familiar with the situation said Chicago Bears linebacker Jonathan Bostic has been fined $21,000 for a hit during last week's exhibition game against San Diego.
Pittsburgh Steelers rookie running back Le'Veon Bell has been ruled out of Saturday's game against Kansas City because of a right foot injury.
Bell underwent an MRI exam Tuesday and Coach Mike Tomlin said he would wait for a second opinion before making a determination about Bell's long-term status.
The Pittsburgh Post-Gazette reported that Bell would be sidelined for six weeks.
A story on the team's website said Lee's deal is worth about $42 million but could escalate as high as $51 million depending on incentives.
