Sanchez was released by the Jets last Friday, a few hours before they signed former Eagles quarterback Michael Vick to a one-year contract. While Vick is expected to compete for a starting job, Sanchez will be brought in to vie with Matt Barkley for the backup spot behind Eagles starter Nick Foles.
"It's a position of need for us," Eagles coach Chip Kelly said Wednesday at the meetings. "We played three quarterbacks last year. I don't think you can look at your roster and ever say, 'We're good at quarterback.' "
While Kelly has praised Barkley and said that he expects him to take a step forward with a full offseason and his shoulder at full strength, he has not endorsed the Eagles' 2013 fourth-round draft pick as the No. 2 quarterback.
The 6-foot-2, 227-pound Sanchez started in his first four seasons and compiled a 33-29 record in the regular season. He completed 55.1 percent of his passes for an average of 195 yards a game with 68 touchdowns against 69 interceptions in 62 starts. He has a 4-2 postseason mark and played in two AFC championship games.
"Mark is a very, very good athlete," Kelly said. "He's got great experience. There's a lot of positive qualities to him."
Kelly saw Sanchez up close for two seasons in college. In Sanchez's final year at Southern California, he completed 19 of 28 passes for 332 yards and three touchdowns in a victory over Oregon. The Eagles' top three quarterbacks all played in the Pac-10 against Kelly's Oregon team.
Foles went to Arizona and Barkley also went to Southern Cal. G.J. Kinne, who spent part of last season on the practice squad, is also on the roster.
The Eagles are expected to hold a news conference with Sanchez on Friday after an agreement is officially announced.
