FLORHAM PARK, N.J. -- Dustin Keller said he is hopeful that he can get into a practice, perhaps even the game in Buffalo this week. But it sounded like optimism in a season where he has been hampered by a quad injury, and now a "high-grade" ankle sprain.

The tight end did not practice on Thursday.
