Quarterback Aaron Rodgers took part in position drills in Tuesday's practice portion open to the media, one day after Green Bay Packers coach Mike McCarthy said the chances of Rodgers playing Thursday at Detroit were "slim to none."
McCarthy said following Tuesday's workout that his projection is unchanged.
"It does not look like Aaron is going to make it," he said of Rodgers playing in two days.
Of his long-shot odds to play, McCarthy said Rodgers should be considered closer to slim than none.
Matt Flynn took the starter reps, but McCarthy did not name him the starter. Flynn entered in the third quarter last week with the Packers trailing 20-7 and helped Green Bay force a tie in overtime. The last time he started a game for the Packers, Flynn passed for 480 yards and six touchdowns on Jan. 1, 2012 - against Detroit.
"I actually just went back and watched that game again this morning," Lions coach Jim Schwartz said. "It's probably about the 10th time I've watched that game over the last couple of years. We didn't play well. I give credit to him, also. ... We didn't play well enough through that game."
Rodgers is recovering from a broken collarbone. He said last week he wants to play in the Thanksgiving Day game against the NFC North-leading Lions. McCarthy, though, said part of his job is protect Rodgers from himself.
That likely means not exposing him to possible re-injury.
Tuesday was Rodgers' first practice since cracking his collarbone on Nov. 4 against the Chicago Bears. Thursday's game at Ford Field will be the fourth for the Packers without Rodgers.
The light work with quarterbacks Flynn and Scott Tolzien does not mean Rodgers was cleared for contact. Rodgers was officially listed as a "limited participant."
Schwartz still spent some prep time on Rodgers.
"Obviously we have game plans ready for all those different things," Schwartz said. "Whatever quarterback they throw out there, we'll be ready. We've looked at all three of them that have potential to be able to play in this game."
The running joke has been that Flynn owes the Lions a debt of gratitude. Largely off the strength of that 480-yard game, he signed a three-year, $26 million contract with the Seattle Seahawks. He spent one year as a backup with the Seahawks last season and has been released by Oakland and Buffalo this year.
"He came in to the game the year before (2010) when Rodgers went out and we won," Schwartz said. "We won a pitcher's duel - 7-3. We made it difficult on him in the second half of that game. Maybe he would have made more if not for that game. I don't know."
