Rams' Jackson misses practice

St. Louis Rams running back Steven Jackson missed practice Wednesday with lower back spasms, but he expects to play Sunday against Seattle.

Jackson is second in the NFL with 1,031 yards rushing and 1,262 yards from scrimmage. He says he is day-to-day.

Jackson says he wasn’t hurt on any particular play during the Rams’ 21-13 loss to Arizona on Sunday, describing the injury as “wear and tear of the year.”

In 10 career regular-season games and one playoff game against Seattle, Jackson has 757 yards rushing (68.8 ypg). He has never rushed for more than 93 yards against the Seahawks.

Rams guard Richie Incognito was restricted to conditioning work on Wednesday and is likely to miss a fourth straight game with a foot injury.

Rookie offensive tackle Jason Smith did not pass baseline tests for what coach Steve Spagnuolo termed a mild concussion. Spagnuolo said Smith would take the test again today.

New York Jets wide receiver David Clowney said he was stunned after someone hacked into his Twitter account and sent out a series of vulgar messages.

“I was very shocked,” he said. “There was nothing I could do about it.”

Clowney has had his Twitter account locked since the obscene tweets went out to friends and fans Monday, and the receiver said he might not use the social networking site again.

He also denied speculation by some that he was really behind the messages and was just trying to cover his tracks by claiming he was hacked.
