TEMPE, Ariz. (AP) - The Arizona Cardinals opened their three-day minicamp with intense competition for three spots on the offensive line.
Tight end, right tackle and right guard are up for grabs with no clear front-runner.
Coach Bruce Arians says any decision won't be made until the players don pads and practice in training camp, which starts in late July.
One of the tight end candidates, second-round draft pick Troy Niklas, broke his right hand last week and Arians says he's out until training camp.
Other candidates at tight end are free agent signee John Carlson and returnees Rob Housler and Jake Ballard.
