Keisel re-signed with the Steelers on Tuesday, ESPN's Adam Schefter reports. The Cardinals were said to be making a push for Keisel after losing Darnell Dockett to a season-ending knee injury a day earlier, but the longtime Steeler will once again be donning the black and gold. Keisel started all 12 games he was active for last season, racking up 29 total tackles and four sacks. Given his experience in Dick LeBeau's 3-4, there's a good chance he'll beat out Cam Thomas to earn one of the starting roles at defensive end.
