Sight is a fairly important sense, especially when your job is finding holes and blasting through them.
Green Bay Packers running back Eddie Lacy has had a tad bit of trouble with that aspect of life the past few days, limiting him in the last two practices because of eye irritation due to a contact lenses problem.
Saying he's "very blind" and displaying his inability to see across the room without the contacts, Lacy told reporters Thursday that his eye started bothering him after wearing his contacts past their normal 30-day shelf life.
The bulldozing runner said he would use the contacts again this weekend and rebuffed a suggestion he go with goggles.
"I refuse," Lacy said before backtracking slightly, per ESPN.com. "I don't want to say I refuse because I might, because I think it will be better than wearing contacts, but that's kind of old school."
Let this be a lesson -- don't wear 30-day contacts past their shelf life. Lacy's vision problems should be worked out by the weekend, but this is something to monitor. His vision is crucial to his ability to know when to cutback or use his patented spin move.
