Here's Glazer via Twitter:
The team confirmed Jackson's status moments ago via Twitter. There is also no indication of just how much action Jackson will see today. Cadillac Williams will play today, and it is possible that Jackson will see his touches trimmed as the Rams proceed cautiously around his injury.
Jackson strained his quad on the first play from scrimmage against the Eagles in the Rams season opening loss.
Limited or not, the Rams will be happy to have Jackson back. Earlier today, Jackson's agent, Steve Caric, signaled a possible return for his client, noting that he had started him on his fantasy team (conflict of interest?). Jackson may see some targets as a passing option as well, giving the Rams a physical player to matchup with the Ravens' linebackers.
