GREEN BAY, Wis. -- The last time Jordy Nelson had a hamstring injury, he missed four games.
Green Bay Packers coach Mike McCarthy does not think his star receiver has anything anywhere near as problematic this time.
"I think it's day to day," McCarthy said.
But Nelson did not practice on Monday, and it became clear why he was held out of the preseason opener at Tennessee two days earlier. Unlike quarterback Aaron Rodgers and running back Eddie Lacy, who were held out by McCarthy, Nelson was not a healthy scratch.
According to McCarthy, Nelson also did not participate in the team's closed practice on Friday.
Nelson attended practice on Monday but did not participate. Near the end of the session, he did some leg exercises off to the side.
He made only a brief appearance in the locker room and when asked about his hamstring, he said: "I told you I was fine two years ago."
Except that he wasn't, which makes Nelson's comment Monday rather ambiguous.
In 2012, Nelson pulled a hamstring in practice leading up to the Week 8 game against Jacksonville. He did not play against the Jaguars but returned to start the next four games only to re-injure his hamstring in Week 13 against Minnesota. He missed the next three games.
After signing Nelson to a four-year, $39 million contract extension last month, the Packers will want to make sure Nelson does not have a recurrence of the injury like he did in 2012.
Last season, Nelson missed all but one series of the preseason because of a knee injury that required surgery. He returned in time for the regular-season opener and went on to his best season with 85 catches for 1,314 yards and eight touchdowns.
Two other previously unreported injuries came out of Saturday's game. Rookie receiver Davante Adams sustained a wrist injury and defensive end Josh Boyd injured his ribs. Adams said the injury occurred on the second of his two muffed punts but he stayed in the game despite feeling some discomfort. The X-Rays were negative.
McCarthy said the two injuries that were reported immediately after the game -- running back Rajion Neal (knee) and linebacker Joe Thomas (knee) -- were not serious. Although neither of the rookies practiced on Monday, they were not classified as long-term injuries.
