ALLEN PARK -- Second-year Detroit Lions running back Sione Vaki exited Monday’s practice early with what team officials are calling a leg injury.

Two Detroit Lions backups, defensive tackle Roy Lopez and running back Sione Vaki, are expected to be out for a few days, coach Dan Campbell said.

Lions coach Dan Campbell said that Anzalone performed well on his conditioning test and refuses to believe that the linebacker is holding in. The fifth-year coach stated that his defensive captain has been sidelined with a hamstring injury to this point in camp.

Though he said he wishes to retire as a member of the team, Detroit Lions linebacker Alex Anzalone admitted he was "disappointed" with the state of contract negotiations between himself and the team as he enters the final year of his current deal.
