Sources: EJ Manuel expected to start Sunday against Bengals

— -- EJ Manuel is expected to start at quarterback Sunday for the Buffalo Bills in place of the injured Tyrod Taylor, sources told ESPN's Bob Holtzman.

Manuel took the majority of first-team snaps at practice this week as the Bills prepared to host the undefeated Cincinnati Bengals.

Taylor, who is officially listed as questionable with a knee injury, has been unable to convince Rex Ryan and the Bills' coaching staff that he will be ready to play, sources told Holtzman.

The Bills have not publicly named a starting quarterback yet for this week. Ryan said Friday that Taylor is "feeling a lot better" but would be a game-time decision.

Manuel was Buffalo's first-round draft pick in 2013 but lost the starting job to Taylor during the preseason. The 25-year-old Manuel appeared in five games last season, completing 58 percent of his passes for 838 yards, five touchdowns and three interceptions.

Taylor, 26, has sparked the Bills to a 3-2 record in his first season as a starting quarterback. He suffered a sprained MCL in last week's victory over the Tennessee Titans and has been limited at practice this week.
