The five-time Pro Bowl selection, whose start to the 2012 season was hampered by a torn Achilles tendon, suffered the injury during the fourth quarter of Sunday's 23-20 loss to the Pittsburgh Steelers.
"We kind of live by the creed, 'If you can breathe, you can play', but we just got to check it," Suggs, the American Football Conference's defensive player of the year in 2011, told reporters on Wednesday.
"We got to see how it holds up throughout the week. It will definitely be a game-time decision on Sunday. If it's a possibility I can play, then I'm going to play."
Asked if he been at all worried that the biceps tear could force him to shut down his season, Suggs replied: "That's not an option for me. Definitely, I will continue to line up at some point this season.
"It all depends on when it starts to get better and how much I can really do on it."
Suggs missed six games at the start of the season after tearing an Achilles tendon during the offseason but said he did not feel disheartened following his latest injury.
"I'm in really good spirits about it," the 30-year-old said. "I'm not beat down about it."
