The NFL pre-season is all about the 32 teams preparing for the year and deciding who will be representing their franchises this year.
While preparation is a key part of the off-season and training camp, it could be argued that the biggest part of the off-season is also to avoid suffering too many injuries.
Big hit to Green Bay
Several teams are currently dealing with a long list of injured players but arguably the biggest injury concern of the off-season so far has come from Green Bay.

The Green Bay Packers have spent the last day concerned over one of their top wide receivers in Jordy Nelson who suffered an injury this weekend.
The Packers lost their second pre-season game as they were on the road to the Pittsburgh Steelers on Saturday.
Pittsburgh won the game 24-19 but the biggest news was the suspected ACL injury to Nelson which could be seen as a season derailing blow.
The Packers have now confirmed that Nelson will be out for up to a year and will miss the entirety of the 2015 NFL season.
However, Green Bay failed to confirm what the exact injury is that Nelson has suffered but reports have suggested that it is a torn ACL.
"It was determined that WR Jordy Nelson sustained a significant right knee injury in yesterday's game at Pittsburgh... He will miss the remainder of the season." - Packers statement on Jordy Nelson
Green Bay had been one of many peoples tips to make a run to Super Bowl 50 this year but without one of their top wide receivers, can they still hope to contend with the likes of the Seattle Seahawks, Dallas Cowboys or even the other teams in their quickly improving division?
The first hurdle
Green Bay's first challenge next year will be to once again claim the NFC North divisional title, but that may prove more difficult now.
The division was already improved with the Minnesota Vikings now with the returning Arian Peterson and some other impressive off-season signings.
The Detroit Lions have lost Ndamukong Suh but are still looking strong so far in the pre-season and will offer a good challenge to the Packers once again next year.
However if there is one man you would want under centre after you've just lost Jordy Nelson, it would probably be Aaron Rodgers.
