The Facts: HC John Fox told reporters during his Monday press conference that Rosario suffered a foot sprain in Sunday's win over the Chargers.

Diehards Line:Those interested will want to watch for practice updates as the week progresses. Rosario is clearly the team's receiving weapon of choice at tight end as he demonstrated with his game-winning catch in San Diego. Assuming he's healthy enough to play, Steve Smith's ongoing absence should continue to lead to more opportunities for Rosario.
