The Dallas Cowboys' offensive line was a truly dominant force in 2014 and they are hoping that, having made more additions this offseason, it will be a game-deciding factor once again in 2015.
Unfortunately, those plans were put in doubt today with news that one of last year's standout performances, Zack Martin, has suffered a "scary" injury.
The second year offensive guard went down during Monday's training camp practice, Cowboys owner, Jerry Jones, describing it as a potential nerve issue in the shoulder/neck area.
Speaking after practice, the Cowboys hierarchy were hopeful that Martin's injury was just a "stinger" but they made it clear that he would require further evaluation after the scary incident - fears that it could be a long-term issue clearly prevalent.
"For sure a stinger. We've got to obviously do a lot of work there to make sure that is all it is," explained Dallas Cowboys VP Stephen Jones.
"Scary...Obviously concerned. Hopefully that's all it'll be. Keep fingers crossed and hopefully he'll be fine."
Martin was able to walk off the practice field under his own steam rather than on a cart but at this stage his prognosis is still unknown.
Having transitioned into the pros with ease in his rookie year - he achieved Pro Bowl honers in 2014 - Dallas fans will be hoping that Zack Martin hasn't suffered any lasting damage that could affect his second year in the NFL. Especially considering the Cowboys' injury issues at present.
Fellow guard Ron Leary is already suffering with a back injury, whilst tackle Doug Free is recovering from offseason surgery and Tyron Smith (left tackle) is dealing with a bicep issue.
