Velus Jones' concern over aggravating his hamstring injury was apparently well founded.
On Thursday after Jones had practiced Wednesday for the first time in three weeks, he was back on the sideline with the hamstring issue. He was the only one missing practice with an injury for the Bears.
Jones said after Wednesday's practice that part of the reason he came back during preseason and then was gone again was he had aggravated the injury. Apparently he had another setback after Wednesday's practice, and the Bears could have used his speed at receiver, out of the backfield or on returns this week.
