Battered Grbac Might Sit

First a concussion, then bruised ribs. After getting banged around on successive weekends, Baltimore Raven quarterback Elvis Grbac might be forced to give his battered body a rest Sunday.

Backup Randall Cunningham ran the first-team offense Wednesday and could get his first start with Baltimore against Jacksonville.

Grbac did not practice and is listed as questionable.

Denver Bronco running back Terrell Davis, who had arthroscopic knee surgery five weeks ago, was surprised when told of news reports saying he may have a stress fracture in his leg and might be lost for the season.

The speculation surfaced on CNNSI.com and the Baltimore Sun, which reported that a trade between Denver and Baltimore fell through because of uncertainty about Davis’ health.

Both stories, citing unidentified NFL and Raven officials, said the Broncos were reluctant to trade backup running back Olandis Gary because they were worried Davis may not return this season.

“I’m on schedule to play this Sunday,” Davis said.
