The Detroit Lions held their annual kickoff luncheon on Wednesday to introduce the team to fans.

But Ziggy Ansah, the team's first-round pick and one of their prized pickups in the off-season, was nowhere to be found, according to the Detroit News.

Ansah has been absent fron the Lions' past three practices after initially suffering what was speculated to be a concussion on Saturday.

However, Coach Jim Schwartz has been silent in relaying what the injury to Ansah is, only further fueling speculation that it could be a concussion.
