A government official said Monday that investigators probing the friendly fire death in Afghanistan of former football star Pat Tillman found no criminal negligence. The findings end a yearlong inquiry into the conduct of the U.S. soldiers who shot Tillman in 2004 and a possible subsequent cover up. The Army announced in March 2006 it would open a new investigation into the circumstances of Tillman's death, in response to complaints from Tillman's family and congressional representatives that previous probes had left key questions unanswered.

The Arizona Cardinals signed fullback Terrelle Smith and defensive lineman Chris Cooper to two-year contracts. Terms of the deals weren't released.

A Pentagon investigation will recommend that nine officers, including up to four generals, be held accountable for missteps in the aftermath of the friendly fire death of Army Ranger Pat Tillman in Afghanistan, senior defense officials said. The Defense Department inspector general will cite a range of missteps and inappropriate conduct as the military probed the former football star's death on the battlefront in 2004, said one defense official. The official, who requested anonymity because of the sensitivity of the issue, said it appears that senior military leaders might not have had all the facts or worked hard enough to get the facts of what happened on that day in April 2004.

The Cardinals re-signed linebacker Monty Beisel to a two-year contract Wednesday. Beisel played in eight games for Arizona last season, including two starts. He signed with the Cardinals as a free agent last November after being released by the Patriots.

Former Cowboys running back Emmitt Smith has been hired by ESPN as a studio analyst for its NFL pregame coverage. Smith, the National Football League's all-time leading rusher, will appear on the network's NFL Countdown and Monday Night Countdown shows. He will also appear as an analyst on ESPN Radio and ESPN.com, the network announced Monday.

The Cardinals fired wide receivers coach Richie Anderson on Monday, four days after his arrest in a police prostitution sting operation. Anderson, a fullback in the NFL for 13 seasons, was hired by new Cardinals coach Ken Whisenhunt in January. Anderson, 35, was arrested Thursday night on an accusation of soliciting an undercover Phoenix police officer posing as a prostitute.

Former No. 2 overall pick Leonard Davis became the richest offensive lineman of this year?s free-agent class when he agreed to a seven-year, $49.6 million contract with the Cowboys on Sunday. The deal eclipses the seven-year, $49.5 million pact that Eric Steinbach received from Cleveland on Friday. The plan for Davis, who spent the first six years of his career with Arizona, is to play either right tackle or right guard for the Cowboys. Dallas is trying to re-sign right tackle Marc Colombo. If the Cowboys do that, Davis will play right guard.
