Heading into an offseason in which he's due to become an unrestricted free agent, Bears SLB Pisa Tinoisamoa said he's unsure if he will be back with the Bears or even if he'll be playing with any team in 2011. "I don't know if this is the end for me," he said earlier this week at Halas Hall. "It would be ignorant of me to say that it couldn't be that way." Tinoisamoa missed time with right knee issues in each of his two seasons in Chicago. He started 10 regular-season games and the NFC championship game this season, but missed four games in the second half of the season and underwent arthroscopic knee surgery in early December. PFW asked Tinoisamoa if he's confident his knee will be healthy enough to allow him to keep playing in 2011. "I think so, but maybe that's just that old stubbornness in me," he said. "I don't know. I feel like I could keep on playing. I'm excited to get healthy and have another shot."
