The Philadelphia Eagles' offensive line is already going to be tested when the regular season starts.
Right tackle Lane Johnson is practicing with the Eagles but will be suspended for the first four games for violating the policy regarding performance enhancing drugs.
In addition, backup guard and center Julian Vandervelde underwent back surgery and is likely out for an extended period of time.
Look for David Molk to get every chance to step up.
Molk played 41 snaps with the second team in the Eagles' preseason loss at the Chicago Bears on Friday. He signed with the Eagles as a free agent in February to help bolster their depth.
"The only sad thing is this is how the NFL works," Molk told the Wilmington (Del.) News Journal. "Your gains come off someone else's hurt, which is terrible, but it's the business."
Center Jason Kelce has been thoroughly impressed with Molk thus far in training camp.
"David has really stepped up for us, and that's been huge for us," Kelce told the News Journal. "If Julian had gotten hurt and we [didn't] have another guy, that would have hurt some of the depth. But right now, Molk is playing just as good as me. He's doing really well right now."
Vandervelde played in 14 games for the Eagles last season with much of that work coming on special teams.
