The Dolphins waived Gronowski on Friday.
Gronowski caught on with the Dolphins in early May as an undrafted free agent, but the Iowa product will look for opportunities elsewhere, assuming he clears waivers. During his final season as a Hawkeye, Gronowski completed 63.0 percent of his passes for 1,741 yards, 10 touchdowns and seven interceptions while turning 130 carries into 545 yards and 16 scores across 13 games.
