Free-agent running back Willie Parker is scheduled to visit the St. Louis Rams on Friday, a league source told NFL Network's Jason La Canfora.
Parker, whose four-year, $13.6 million contract expired after the season, began 2009 as the Pittsburgh Steelers' starter. However, he suffered a Week 3 turf toe injury that kept him out for two games and hampered him for the rest of the season.
Rashard Mendenhall took over in Week 4 and never relinquished the Steelers' running back job, making 12 starts.
Parker -- who has posted three 1,000-yard seasons -- rushed for 398 yards without a touchdown in 14 games last season, and he had only one receiving score.
The Rams are seeking depth behind running back Steven Jackson, who dealt with a back injury last season. The team announced Thursday that it has brought back Kenneth Darby, who was among Jackson's backups last season.
Fullback Jason McKie visited the Rams on Thursday, a league source told La Canfora. McKie was released by the Chicago Bears after seven seasons with the team.
Long snapper Chris Massey, a seventh-round draft pick by the Rams in 2002, also will return, the team said. Massey ended last season on injured reserve after undergoing knee surgery in October.
