Vincent and Simon had some personal business yesterday and are expected to rejoin the team for this morning's workout.
Taylor and Staley, on the other hand, are unhappy with their contract situations and will not be in attendance at any of the eight minicamp workouts that are designed to prepare the team for the start of training camp next month.
Asked if he was disappointed by the players' failure to attend, Reid offered only guarded comments.
"I'm not going to get into all that," he said. "That's not my style. They're for personal reasons so I've got to be sensitive to that."
The Eagles cannot fine the players because this minicamp is voluntary. The only recourse they would have with Taylor and Staley would be to release them, and there was no indication that was going to happen.
Agent Jason Medlock unsuccessfully tried to engage Eagles president Joe Banner in talks about a contract extension for Taylor yesterday morning. A lack of success on that front left the Pro Bowl cornerback feeling jilted by the only NFL employer he has ever known.
"I want to be an Eagle," Taylor said from Medlock's office in Houston. "That's the most important thing. I think there has been a lack of communication. I'm not trying to force anyone into doing a deal. I think after the years and the work I put in with the Eagles, I deserve to know whether I'm going to be a part of their future or not."
Regardless of what happens, Taylor said he would report to training camp on time next month.
Staley's camp, meanwhile, did not speak publicly about the running back's reasons for declining to attend the minicamp. His agent did not return phone calls yesterday.
It's worth noting that both players are going into the final year of their contracts only because those pacts include void options that were triggered by their accomplishments last season.
