Telvin Smith, Allen Hurns out for Sunday's game against Indianapolis

JACKSONVILLE, Fla. -- The Jacksonville Jaguars won't have a defensive starter for the first time this season with linebacker Telvin Smith ruled out of Sunday's game against Indianapolis because of a concussion.

In addition, receiver Allen Hurns (ankle) and backup offensive lineman Josh Wells (concussion), who has started the past three games, will not play. Right tackle Jermey Parnell (knee), left guard Patrick Omameh (quad) and linebacker Lerentee McCray (hamstring) are questionable. Parnell is expected to play.

Smith suffered the injury in the first half of last Sunday's loss at Arizona and did not practice all week. He is the Jaguars' leading tackler (83), including a team-high 11 for loss, and has three interceptions, five pass breakups, a forced fumble and a fumble recovery. Rookie Blair Brown will get additional playing time in Smith's absence.

Parnell has missed the past three games after hurting his left knee against Cincinnati on Nov. 5 when the Jaguars were at the Bengals' goal line trying to run out the clock. He hasn’t played since, and his replacement (Josh Wells) has struggled as a run-blocker because he's not as powerful as the 6-foot-6, 326-pound Parnell.

Omameh injured a quad against the Chargers and left the game in the second half. He has missed the past two games. Backup Chris Reed has started both games.
