Finley suffered a bruised spinal cord in his neck when he was hit by Tashaun Gipson during the Packers' 31-13 victory over the Cleveland Browns on Sunday, being treated for six minutes on the field before being taken off to an intensive care unit.
However, the tight end is reportedly recovering well in hospital and could be released as early as tomorrow, leaving Bostick in no doubt that he will return to action.
"You know Jermichael, he's a competitor; he definitely wants to play. I definitely think he'll be back as soon as he can," Bostick is quoted as saying by ESPN.
The Packers have a 4-2 record so far this season and will face the struggling Minnesota Vikings in their next match on Sunday.
