The Jacksonville Jaguars made four roster moves today, placing safety Donovin Darius on injured reserve, and signing rookie wide receiver Charles Sharon from the practice squad. The Jaguars also re-signed offensive tackle Wayne Hunter and defensive back David Richardson to the practice squad.

Darius, 31, had started all 10 games this season at strong safety after returning from a knee injury in 2005. The ninth-year veteran broke his leg in the first quarter of the Jaguars win on Monday night and had surgery to repair his leg yesterday in Birmingham, Ala. He was second on the team with 60 tackles and four passes defensed. He holds the team record with 857 career tackles and has 14 interceptions.

Sharon, 23, was originally signed by the Jaguars as an undrafted rookie free agent out of Bowling Green. The 6-0, 184-pound receiver has spent the first 10 weeks on the Jaguars practice squad after playing in all four preseason games. He joins Rashean Mathis, Dee Webb and Jamaal Fudge, who are natives of Jacksonville and he attended Palatka High School.

Quarterback Byron Leftwich also underwent surgery on Tuesday on his injured left ankle. The surgery took place in Birmingham, Ala. Leftwich remains on the active roster.
