The Detroit Lions cut five players to get down to the 80-man roster limit ahead of Tuesday's 4 p.m. deadline, including quarterback Jordan Ta'amu.
Ta'amu signed last week to help alleviate mounting injuries the Lions were dealing with at the quarterback position.
Both Tim Boyle (ankle) and David Blough (shoulder) missed a day of practice last week, but returned for Saturday's preseason loss to the Pittsburgh Steelers.
Ta'amu did not play against the Steelers, and did not throw any passes during the one-on-one portion of Monday's shortened practice. Neither Boyle nor Blough practiced Monday.
