HENDERSON, Nev. -- Geno Smith has added another chapter to his roller coaster season as the starting quarterback for the Las Vegas Raiders . In last week's loss to the Denver Broncos , Smith suffered a right shoulder injury, which will keep him out of Sunday's road matchup against the Philadelphia Eagles ( 1 p.m. ET / Fox ).

Before Smith's injury, his production hadn't met his or the team's expectations when the 35-year-old signal-caller was traded from the Seattle Seahawks in the offseason. Through 13 games, Smith has thrown for 2,648 yards with 16 touchdowns and 14 interceptions. He also has a completion rate of 67% and a QBR of 32.5 -- ranked 30th in the league.

Here's everything you need to know about the Raiders' quarterback situation ahead of Week 15's contest.
