An MRI exam on the injured big toe of Washington Redskins wide receiver Taylor Jacobs revealed a sprain that will sideline him at least a week, the team said yesterday.

Jacobs injured his left big toe while making a cut during the Redskins' scrimmage with the Ravens on Saturday in Baltimore and was unable to participate in the 11-on-11 drills. His toe remains moderately swollen, according to the club's medical update, and Jacobs will be reevaluated at the end of the week. The Redskins are hoping that 2005 will be a breakthrough season for the receiver, who was selected 44th overall in the 2003 draft but has failed to secure regular playing time.

The team expects Jacobs to make an impact as its third receiver -- Washington plans to incorporate more three- and four-receiver sets -- and he will again miss a portion of training camp, something that dogged him last season. Jacobs missed two days last week with the flu and it is highly unlikely he will participate in Saturday's preseason opener in Carolina.

Bubba Tyer, the team's director of sports medicine, described the injury as a "significant strain," after Saturday's scrimmage, and X-rays at the time were negative. The Redskins traded their top two receivers from last season -- Laveranues Coles and Rod Gardner -- and do not have much depth at the position. With Jacobs out, Darnerien McCants and Kevin Dyson figure to gain playing time, as both veterans are fighting for a spot on the team. Wide receiver James Thrash seems a lock to make the team because of his versatility, sure hands and superior special teams play, and newcomers Santana Moss and David Patten are set to start at wide receiver.
