Mike Alstott will be sidelined at least a month after spraining his right knee during Tampa Bay's 19-7 victory over the Chicago Bears.
Alstott, who missed most of last season after neck surgery, was hurt late in the third quarter Sunday when he was tackled for a four-yard loss by Bears linebacker Hunter Hillenmeyer and landed awkwardly beneath a pile. "Four weeks is what our timetable is right now," Coach Jon Gruden said yesterday.
* PANTHERS: The Panthers lost any hope of DeShaun Foster playing again this season when it was determined the running back needs surgery on his broken collarbone.
Foster was expected to miss six to 10 weeks after he was injured in an Oct. 10 loss to Denver; he was placed on injured reserve yesterday.
* COWBOYS: Cowboys wide receiver Terry Glenn will be out at least two weeks because of a sprained right foot. Coach Bill Parcells said the injury won't require surgery but is "pretty severe."
Glenn aggravated his foot in the first quarter of Sunday's loss at Green Bay.
* EAGLES: Running back Brian Westbrook's status for Philadelphia's game against Baltimore on Sunday is uncertain because of a chest injury.
Coach Andy Reid said Westbrook didn't have any broken bones, but was still undergoing tests yesterday.
* RAIDERS: Starting left guard Frank Middleton and rookie wide receiver Carlos Francis have been lost for the remainder of the Raiders' season because of injuries that will require surgery. Also, four-time Pro Bowl cornerback Charles Woodson had an MRI exam yesterday for a hip pointer and his status was uncertain.
* SEAHAWKS: Outside linebacker Isaiah Kacyvenski suffered a high right ankle sprain against Arizona and is doubtful for Sunday's game with Carolina.
