Meanwhile, as Newsome spoke, it was believed the Ravens were making a strong push to sign Crabtree before the nine-year veteran left town and could entertain offers elsewhere.
Crabtree, who spent Friday at the Ravens' facility, becomes the pivotal addition in the team's revamping of the wide receiver position.
Crabtree, 30, has played nine National Football League seasons - six with San Francisco (2009-14) and three with Oakland (2015-17).
The 6-1, 215-pound Crabtree has totalled at least 85 catches in a season three times, including a career-high 89 in 2016.
Crabtree had a solid season with the Raiders in 2017.
Last season, Crabtree caught 58 passes for 618 yards and 8 touchdowns in the 14 games that he played in. The Ravens also officially added deep threat John Brown, who was officially introduced Friday, and Newsome said the team is still active in pursuing a pass-catching tight end.
That's a pretty good deal for Baltimore when you recall the fact that they nearly handed out $29 million to Ryan Grant over four years - A $7.25 million-per-year average.
"We knew he had had an ankle injury in the latter part of the season with the Redskins", Newsome said.
In five career games against the Ravens, Crabtree has 33 catches for 444 yards and six touchdowns.
Brown played four seasons with Arizona before signing a one-year contract this week with Baltimore.
It's a move that completed a Super Bowl reunion and helped fill a sudden void for a possession receiver. Newsome said they have been in contact with agents for both.
