FLAGSTAFF, ARIZ. ? Arizona’s depleted defensive line took another hit when rookie tackle Nate Dwyer broke his left hand.

The injury occurred shortly after the team signed free agent defensive end Gillis Wilson, who spent time with Carolina and the New York Giants the past two seasons.

Dwyer, a fourth-round draft pick out of Kansas University, was injured during the team’s lone workout of the day at Northern Arizona University.

“He really didn’t know what he did,” coach Dave McGinnis said. “He didn’t know he was hurt until somebody told him in the huddle, ‘Man, what’s wrong with your hand?’ He looked down there and it looked like Fred Flintstone, with a big bump on it.”
