Andrews (undisclosed) worked out on a side field Wednesday and looked comfortable running, Jamison Hensley of ESPN.com reports.
Andrews has missed practice for about a week now but seems to be on track for the Ravens' Sept. 10 season opener versus Houston. The Ravens haven't said much about Andrews' injury, apart from head coach John Harbaugh noting last week that it's "nothing serious" and just "something we're kind of working through." In the event of a setback, Isaiah Likely would fill in for Andrews as Baltimore's top receiving tight end.
