Foxborough, Mass. ? New England Patriots rushing leader Sammy Morris was placed on injured reserve Friday, ending his first season with the team.

The Patriots listed linebacker Mike Vrabel, tight end Benjamin Watson and free safety Eugene Wilson as questionable for Sunday’s game at Indianapolis between the NFL’s only unbeaten teams.

Morris was hurt in the sixth game, a 49-28 win at Dallas, and left the locker room with his left arm in a sling. The team said he had a chest injury. He was inactive for the past two games. He still leads New England (8-0) with 384 yards on 85 carries after signing as a free agent from Miami.

Laurence Maroney, the Patriots first-round draft pick last year, should continue to do most of the running Sunday against the Colts (7-0). Maroney has rushed for 358 yards on 74 carries.

Kevin Faulk, primarily a third-down back and a solid receiver, also has seen more action since Morris was hurt.
