The Arizona Cardinals activated linebacker Deone Bucannon from the physically unable to perform list on Tuesday.
Bucannon underwent surgery on his right ankle in May on the heels of missing the final three games of the regular season.
The 24-year-old Bucannon had 91 tackles in 13 games last season. He has posted more than 80 tackles in each of his three NFL seasons and has five sacks, four fumble recoveries and one interception.
Haason Reddick, who is the team's first-round pick, has taken first-team reps in Bucannon's absence.
