Coach Gus Bradley said it's possible that Posluszny could play with his hand in a cast and heavily wrapped.
Bradley says, ''We're just waiting to see about his availability. We do know that if he played, he would play with a cast on. ... The big thing would be the challenge to see what he can do with a club if that's what it is.''
Posluszny injured his hand late in a loss to Tennessee on Sunday.
Also Wednesday, fellow linebacker Dan Skuta (groin) returned to practice in a limited capacity. He has missed three of the last four games.
