Raiders had become one of the least desirable teams to play for. In addition, with the Miami Marlins obtaining their own ballpark in 2012, the Raiders became the last team in the NFL to still share a stadium with a baseball franchise. The baseball infield for the Oakland Athletics at the Oakland Coliseum was present during Raiders games during the early NFL seasons. The end of the MLB season correlated with the beginning of the NFL season, which forced the Raiders to play certain games on a dirt field. The Raiders began 2012 by losing a very poorly executed home opener on Monday Night Football to San Diego 22–14. The team was plagued by fumbles and dropped passes, and did not score a touchdown until near the end. On the bright side, defensive performance was decent and helped contain the Chargers' passing game. After another miserable loss in Miami, the Raiders returned home to take on Pittsburgh in Week 3. In the 4th quarter, trailing by 10, wide receiver Darrius Heyward-Bey collided with Pittsburgh safety Ryan Mundy and was knocked out of the game. The loss of Heyward-Bey inspired the rest of the team, which rallied to tie the game 31-31, and with 4 seconds left, Sebastian Janikowski kicked a 43-yard field goal to win the game 34–31. In the end though, the Raiders finished the 2012 season 4–12. During 2013, there was little apparent sign of improvement as the Raiders once again finished 4–12, including a particularly embarrassing loss to the Eagles in Week 9 when quarterback Nick Foles threw a record seven touchdown passes. In Week 15, they gave up 56 points to the Chiefs. In 2014, Dennis Allen was fired after a 0–4 start and replaced by former Dolphins head coach and then-Raiders offensive line coach Tony Sparano for the remainder of the season. They became the first team to be mathematically eliminated from playoff contention and were guaranteed a fourth-place finish in the AFC West after a loss in Week 11 dropped them to 0–10. The Raiders were the last team in the league that year to win a game, finally doing so the next week against their division rival, the Kansas City Chiefs, but they were defeated 52–0 by the Rams the next week. The Raiders did manage to defeat their geographic rival, the San Francisco 49ers, and defeated Buffalo in Week 16, which mathematically
