The Chicago Bears are suffering one of their worst starts to a regular season, and there are major concerns that things could still get worse.

The Bears got their season up and running by hosting the Green Bay Packers at Soldier Field, and although Chicago did put up a good fight, the Packers were ultimately too strong, sending the Bears crashing 31-23.

Week 2 got much worse as they were trounced by the Arizona Cardinals in a 48-23 defeat as the Bears' defense seemingly went missing.

Last week they went on the road with hope that a change of venue could freshen things up for their players and allow them to claim their first win. They came up against a Seattle Seahawks team that had also lost their opening two games and looked low on confidence. However, things went from very bad to even worse as the Bears were completely shut down in a 0-26 demolition by the Seahawks.

The Raiders come into today's game on 2-1 and will feel they have a very good opportunity to move to 3-1 against a Bears team in disarray. The Raiders claimed a tight 27-20 victory last week against the Cleveland Browns and will be hoping to build upon that result and make improvements on both sides of the ball.

Earlier this week, Thursday Night Football saw the Baltimore Ravens snap their losing run. The Ravens, entering the nationally televised game on 0-3, managed to steal the win in overtime, to defeat the Pittsburgh Steelers 23-20.

The game had looked like the Ravens were in for another painfully close loss. Over the opening three weeks they had lost games by small margins, and often because they had lost concentration for a period earlier in the game, and simply could not get over the line in their fight-backs.

In the second period in their game against the Steelers they looked like they had done the same thing, allowed Pittsburgh to pile on 10 unanswered points. Coming into the fourth quarter 20-14 down it looked like the Ravens were heading for another defeat and would move to 0-4. However, they finally managed to complete their fightback after failing three times already this season.

The Ravens pulled the game back to 20-20 late on to send the game to overtime, and with momentum on their side, they finally got over the line and completed their first win of the season. That result probably damages the Steelers more than it helps the Ravens though, but the game was a perfect way to get Week 4 underway, and now on Sunday there will be 13 more games taking place as the season becomes even clearer as to who will be competing and who will be falling down this year.
