The Baltimore Ravens lost their dangerous kick returner and No. 2 receiver in the second quarter of Thursday's NFL season opener versus the Denver Broncos. Teammate Brynden Trawick collided with an unsuspecting Jones as the latter was preparing to field a punt. Replays showed Jones' right knee hyper-extending. He slammed his helmet to the turf in frustration on the sidelines before departing for the locker room. Jones is doubtful to return, according to the Ravens. Source: NFL.com
