The Bills (3-6) have just two other defensive tackles on their roster, reserves Spencer Johnson and John McCargo.
Stroud was hurt during a 41-17 loss at Tennessee last weekend and hasn't practiced this week. Except to refer to Stroud as day to day, Fewell wouldn't divulge the nature of the injury.
While strong safety Donte Whitner is set to return after missing three games with an ankle injury, the Bills' banged-up defense could be down another regular with rookie safety Jairus Byrd listed as questionable because of a nagging groin injury. A second-round draft pick out of Oregon, Byrd has a league-leading eight interceptions to tie the Bills' rookie single-season record. He also has a five-game interception streak.
Reserve cornerback Ashton Youboty also was ruled out after hurting his ankle last weekend.
Injured linebacker Kawika Mitchell made an appearance in the locker room Friday. Placed on season-ending injured reserve after hurting his right knee in a 6-3 loss to the Cleveland Browns on Oct. 11, Mitchell said he had successful surgery five weeks ago and should be ready to begin working out in March.
