To make room for Pitta on the 53-man roster, Baltimore waived running back Bernard Scott, who has not appeared in a game for the Ravens since being signed on Oct. 28.
On Friday, coach John Harbaugh said Pitta has a "reasonable chance" to play against the Vikings this weekend. Whether he was added to the roster to comply with league rules to make him eligible to play this year or to be in uniform on Sunday will be known tomorrow.
Pitta almost certainly won't be at top form right away, as he missed the first three-quarters of the season and the majority of training camp. But the 6-foot-4 tight end adds a dynamic sure-handed option over the middle, something the Ravens have lacked without him.
Once back to full strength, Pitta would be an asset to the passing game, perhaps softening coverage on the outsides and opening up more opportunities for quarterback Joe Flacco to make plays.
