(The Spread)- Teams aren't even finished with their second full week of training camp and already the landscape in the NFL has changed due to injuries.

On Tuesday evening Percy Harvin tweeted that his hip injury will require surgery. The injury will likely rob Harvin of his entire 2013 season, which is devastating considering how much the Seahawks gave up in order to acquire him from Minnesota in the offseason. It was also reported on Tuesday that Sidney Rice is in Switzerland in order to get "some sort of knee treatment."

In Philadelphia, the Eagles officially placed receiver Jeremy Maclin on injured reserve on Tuesday after he suffered a season-ending ACL injury over the weekend. Riley Cooper will get the first shot to replace Maclin, who is a significantly better playmaker.

The defending Super Bowl champion Ravens were also hit hard over the weekend, as tight end Dennis Pitta suffered a season-ending hip injury. With Pitta hurt, Anquan Boldin in San Francisco, Ed Reed in Houston, and Ray Lewis retired, Baltimore has had a somewhat tumultuous offseason. The Ravens were counting heavily on Pitta with Boldin now a 49er.

According to oddsmakers from online sports book Bovada.lv, the Seahawks are 17/2 to win the 2014 Super Bowl, while the Eagles are 50/1 to win and the Ravens are now 25/1 to win. The Broncos and 49ers remain co-favorites at 6/1, while the Patriots are 9/1 and the Packers are 12/1.
