Davis (undisclosed) did not practice Monday, Jeff Zrebiec of the Baltimore Sun reports.
Coming off a torn ACL suffered last October, Davis was somewhat-surprisingly not placed on the Ravens' PUP list to begin training camp. Assuming he hasn't re-aggravated the injury, when healthy, Davis should be set to compete for the nickelback role he quickly earned in the Ravens' secondary after being acquired from the Dolphins last September.
