Cardinals running back Andre Ellington (knee) and wide receiver Michael Floyd (ankle) are both expected to play Sunday.
Pitta has been out with a dislocated hip since July. He returned to practice Nov. 20.
While he is eligible to play Sunday against the Minnesota Vikings, it is not a certainty. Coach John Harbaugh said Friday that Pitta had a "reasonable chance" of playing.
Pitta is looking forward to playing.
"You always want to see how you're going to respond after getting hit like that," Pitta said Friday. "It's not something that you could simulate in rehab or even in practice. It will be nice to kind of take that first hit and just see how it feels."
Pitta was the Ravens' second-leading receiver last season with 61 catches for 669 yards and seven touchdowns.
Tight ends Dallas Clark and Ed Dickson have combined for 47 catches for 554 yards and three touchdowns this year without Pitta.
The Ravens waived running back Bernard Scott to make room for Pitta on the 53-man roster. Scott did not appear in a game since signing on Oct. 28.
---The Pittsburgh Steelers activated tight end Matt Spaeth from the injured reserve/designated to return list Saturday.
Spaeth, considered one of the best blocking tight ends in the NFL, has been out since preseason with a foot injury.
Spaeth was drafted in the third round by the Steelers in 2007. He returned to Pittsburgh as a free agent this year after spending the previous two seasons with the Chicago Bears.
To make room for Spaeth on the 53-man roster, the Steelers waived tight end Richard Gordon. Gordon signed with Pittsburgh on Oct. 15. He was previously with the Oakland Raiders in 2011-12.
---Detroit Lions rookie cornerback Darius Slay has a torn meniscus in a knee that was injured in practice this week, according to ESPN.
Slay is listed as doubtful for Sunday's game against the Philadelphia Eagles. He was injured Thursday and is reportedly considered week-to-week.
Lions coach Jim Schwartz said Friday it was a "freak" injury that occurred during a non-contact portion of practice.
Slay, who was drafted in the second round of this year's draft out of Mississippi State, has 27 tackles and four pass breakups.
After starting the first two games of the season, Slay has been the Lions' third cornerback behind Rashean Mathis and Chris Houston.
Houston is questionable with a foot injury. Bill Bentley and Jonte Green figure to get expanded roles if Slay and Houston cannot play.
