The Lions didn't receive much good news when they examined a couple injured players after Sunday's win over the Packers.
Coach Jim Caldwell said cornerback Josh Wilson suffered "a pretty significant injury" in the game. Wilson was using crutches to walk around the Lions' locker room after the game and was unable to put weight on his right leg when he exited the field late in the fourth quarter.
Caldwell declined to provide much more information about Wilson's injury, including whether or not he needs surgery or will go on injured reserve with seven games left this season.
"It's not a one-week injury," Caldwell said.
The Lions will also have to be patient with fellow cornerback Nevin Lawson as he suffered a brain injury late in the fourth quarter.
"He's in the protocol, so he's working his way through it," Caldwell said.
Concussions affect each player differently, so it's unclear if Lawson will miss any games.
Either way, with Wilson expected to miss time, the Lions will likely need to add at least one cornerback to the roster this week. Currently, the only healthy ones are Darius Slay, Quandre Diggs and Crezdon Butler.
The Lions could activate rookie Alex Carter from injured reserve with designation for return. The team has two weeks left to decide whether or not Carter will play this year or remain on IR for the rest of the season. Carter, a third-round pick, practiced for the first time in months last week and is still adjusting after missing so much time.
"I think he's moving along, but we'll see if it happens quickly enough," Caldwell said of Carter. "I hope so."
Stanley Jean-Baptiste, who's on the practice squad, has improved, according to Caldwell, so the Lions could promote him if they want. Otherwise, the Lions could look at free agents available, which is how they found Butler. Butler, who was with the team in training camp, signed Saturday and made the key pass breakup on the Packers' 2-point try.
Caldwell said the Lions make acquisitions based on which players can help the team win the next game, so they won't rush Carter back if there's a better option.
