St. Louis Rams right tackle Rodger Saffold suffered a left shoulder injury in the team's preseason game Thursday night at Cleveland and is doubtful to return, the team announced on Twitter.

Head coach Jeff Fisher said Saffold's x-rays came back negative.

Saffold is making the move from left to right tackle after the team's offseason acquisition of Jake Long. Saffold was expected to play more than the regular starters in the preseason, to grow more comfortable with the position change, but was injured on the second offensive play of the game. As a rookie in 2010 he started all 16 games but only played in nine contests in 2011 and 10 in 2012  because of injuries.

A second-round pick out of Indiana, Saffold is entering the final year of his rookie contract.
