Eagles quarterback Michael Vick returned to practice Thursday, just four days after he suffered a concussion against the Falcons in Atlanta.
During the portion of Thursday's practice open to the media, Vick was seen throwing passes to assistant coaches, jogging around with teammates and participating in all the drills that the other quarterbacks, Mike Kafka and Vince Young, participated in.
Vick's participation indicates that he's been cleared by the NFL-appointed independent neurologist, required under the league's 2009 concussion policy for a player to "return to football activities."
With a huge media contingent watching, Vick arrived at practice in full pads and a helmet. He watched practice from the sideline on Wednesday afternoon, after participating in a morning walkthrough.
In order to help protect against future concussions, Vick is planning to refit his helmet with Kevlar padding, the CEO of Unequaled Technologies told ESPN's Sal Paolantonio on Wednesday.
Rob Vito told ESPN that he will meet with Vick in Philadelphia on Friday to refit his helmet to help Vick deal with the post-concussive blows to the head in Sunday's home opener against the New York Giants.
"The 100-year-old foam everybody is using in helmets is antiquated," Vito said. "Concussions are the injury of our age and really they should not be happening anymore."
Vick became a spokesman for Unequaled Technologies in 2010, when the company designed a Kevlar vest for him after he suffered a rib injury against the Washington Redskins in Week 4.
Vick threw for a pair of touchdowns in a 35-31 loss to Atlanta, but couldn't continue after getting spun by a Falcons rusher into one of his teammates, right tackle Todd Herremans. He was replaced by Kafka. Young, who was signed to be the backup, also missed the first two games with a hamstring injury.
Giants coach Tom Coughlin, in a conference call with the media earlier this week, said he expected Vick to play, and that New York was not putting together a different game plan without Vick in it.
Vick has only played a full 16-game regular season once in his career. He missed three games with a rib injury last year.
