TAMPA — If quarterback Josh Freeman is unable to play today against Carolina because of a sore right shoulder, the Bucs will be prepared.
Tampa Bay signed third-string quarterback Rudy Carpenter from its practice squad Saturday in case he needs to serve as the backup to possible starter Josh Johnson.
Freeman was limited in practice all week and threw only soft passes Thursday. He is listed as questionable, but the Bucs have said his status will be determined in pregame warmups.
Johnson, who went 0-4 as a starter in 2009, has taken first-team reps. If Freeman can't play, it would end a steak of 35 starts.
Freeman was injured on the final offensive play of a 23-17 loss to the Titans on Sunday when he dropped the snap on a fourth-and-1 quarterback sneak.
Carpenter, a former Arizona State star, spent 2010 as the Bucs' No. 3 quarterback but was released after training camp and re-signed to the practice squad.
To make room, the team waived linebacker Zac Diles.
SUH UNHURT IN CRASH: Lions defensive tackle Ndamukong Suh crashed his car into a tree in downtown Portland but was not injured, police in Oregon said. They said Suh was not impaired.
QB QUESTION: The Rams activated quarterback Tom Brandstater from the practice squad, possibly a sign that Sam Bradford won't play today. A.J. Feeley would start in place of Bradford, who has a high left ankle sprain.
NEW STADIUM: The 49ers and City of Santa Clara secured funding for a stadium. Goldman Sachs, Bank of America-Merrill Lynch and U.S. Bank agreed to an $850 million loan.
