INJURY REPORT: Left tackle Jermon Bushrod remains limited with what Vitt described as a shoulder ailment. Linebacker Jonathan Vilma, whom Vitt said last week is generally excused from Thursday practices to rehab his surgically cleaned knee and to keep in line with new OTA work-hour rules, was chatting with coaches on the sideline for a moment Thursday but did not participate in drills. Similarly, running back Mark Ingram was on the field but not practicing. Ingram, too, is recovering from a knee cleanup tied to damage in his college days at Alabama.
Vitt also noted that running back Chris Ivory, who has battled a variety of injuries in his two-year NFL career, felt hamstring tightness and was limited.
