Right foot injured vs. Pats to keep Lewis out Sunday

The strained right foot that kept Jamal Lewis out of practice all week will also keep the Cleveland Browns' starting tailback out of the Sunday game against the Miami Dolphins, team officials announced Saturday evening.

Third-year veteran Jason Wright, who replaced Lewis after he was injured in last week's loss to the New England Patriots, will start the fourth game of his NFL career.

Lewis, 28, suffered the injury on the first play last week, after an 11-yard run. An MRI examination showed no structural damage to the foot, but Lewis wore a protective boot for much of the week, while holding out hope he would make enough progress in treatment to enable him to play.

The foot remained painful and swollen, however, and the Cleveland medical staff determined Saturday afternoon that Lewis was not sufficiently recovered to play.

The eight-year veteran has started all five games for the Browns and leads the team in rushing with 382 yards on 77 attempts with two touchdowns. Lewis, who signed with the Browns as a free agent after his release by the Baltimore Ravens this spring, ran for 216 yards in a Sept. 16 victory over Cincinnati, but he has not been over 64 yards in any other game this season.

Although averaging just 3.3 yards per carry in games other than the Cincinnati contest, Lewis remains the focus of the Cleveland running attack.

The Browns are ranked No. 16 in the league in rushing offense and are averaging 110.2 yards per game. Miami has struggled to stop the run this season and is allowing an average of 174.2 yards, second-worst in the league. The Dolphins have also given up an NFL-high eight rushing touchdowns.

Wright, 25, rushed for 59 yards on 15 carries after replacing Lewis last week. For the year, he has 19 carries for 102 yards and no touchdowns. The former Northwestern standout has appeared in 23 games for his career.
