The Lions placed Cabinda (ankle) on the reserve/PUP list Tuesday.
Cabinda has been tending to an ankle injury throughout the duration of training camp and is now required to sit out for at least the team's first four games. The 240-pounder remains the only rostered fullback for Detroit, so it'll be worth monitoring whether the team brings in another lead blocker, which could offer a clue into the severity of Cabinda's ankle issue.
