Harrison (hamstring) doesn't carry an injury designation into Sunday's game against the Raiders, David Furones of the South Florida Sun Sentinel reports.
After back-to-back limited practices Wednesday and Thursday, Harrison was a full participant Friday and is cleared to play Week 1. The 29-year-old signed a one-year deal with the Dolphins in the offseason after logging 29 tackles, including 2.0 sacks, across 10 regular-season appearances with Atlanta in 2025.
