Jets running back Martin to announce retirement this week

Jets running back Curtis Martin, the fourth leading rusher in NFL history who hasn't played since the 2005 season, will make it official this week and announce his retirement from the NFL.

The news that an announcement is imminent was first reported by The New York Post.

The Jets open training camp Friday and are expected to hold a news conference before camp begins to announce the running back's retirement.

Last month, Martin re-worked his contract for a second straight year to provide the team more salary cap room.

Martin tore cartilage in his right knee in Week 2 of the 2005 season against Miami, and aggravated it two games later against Baltimore. He
played through the pain, but ended his season after the Jets' 12th

The five-time Pro Bowler said the knee became a "bone-on-bone" situation when
the damaged cartilage was surgically removed in December 2005. He was
slow to recover and was placed on the Physically Unable to Perform list before training camp
so he could rehabilitate the knee and did not play last season.

Martin spent his first three seasons with New England, and came
to the Jets as a restricted free agent in 1998. His best year was
his last healthy season in 2004, when he led the league in rushing
with 1,697 yards and tied Barry Sanders' record of 10 straight
1,000-yard seasons to start a career.

Martin, 34, has carried 3,518 times for 14,101 yards and 70 touchdowns in 168 games. Only Emmitt Smith, Walter Payton and Sanders have compiled more rushing yards.

After using three different starters at tailback in 2006, and finishing 20th in the league in rushing offense, the Jets acquired Thomas Jones in a trade with the Chicago Bears this spring, and he is the projected starter.
