Wide receivers on different teams are the least of Cam Newton's issues. He should be much more concerned with all the cardio he's going to get while he's running for his life all season. 

The most dangerous thing you can do these days is to put on a Panthers jersey and play offensive line. They've been decimated by the injury bug thus far, which claimed its latest victim.

Carolina's left tackle Matt Kalil missed his second straight practice with a knee injury. 

​​If you're reading this, you might be getting a phone call to play offensive line for Carolina soon.

In just the few weeks since training camp has begun, the Panthers have seen lineman after lineman go down. First, it was All-Pro right tackle Daryl Williams, who dislocated his kneecap and tore his MCL, followed by starting guard Amini Silatolu, who tore his meniscus. Kalil becomes the third starter on this offensive line who could miss time depending on the severity of his injury. 

​​Kalil struggled against the Dolphins recently and left fans more frustrated than pleased, but his absence creates yet another problem on this offensive line. Second-round pick Taylor Moton was originally set to fill in for Williams at right tackle, but now will be moved from his natural position to protect Newton's blindside. 

If this injury plague continues to come down on the offensive line, the Panthers are going to be pulling fans from the stands to line up in front of Newton.
