General manager Howie Roseman called Smith a "versatile guy [who] can play receiver inside and out, has lined up in the backfield. When we're looking at our 46- and 53-man roster, having a guy who can do more things is a plus for us."
Smith, 6-foot-2 and 213 pounds, was a fourth-round draft pick by the New York Jets in 2006. He signed with the Buffalo Bills in 2011 after five seasons in New York. Smith has 101 career receptions for 949 yards, 2,773 career return yards, and 14 total touchdowns.
"I'm excited," Smith said. "In this league, you never know what's going to happen. This team is a great team. I just want to be a part of it, find my way, and earn these guys' respect."
Missing the challenge
Offensive coordinator Pat Shurmur, who advises coach Chip Kelly on replay reviews, said that the video that coaches saw in the booth did not show Packers receiver Jarrett Boykin's elbow go out of bounds on a 36-yard catch in Sunday's game.
The Eagles did not challenge the ruling, a completion. Shurmur said the coaches would have if they had seen the replay in a timely fashion. The coaches are supposed to have access to both the stadium feed and the broadcast feed. There was nearly a minute between plays, and the broadcast feed showed multiple replays during that minute.
"All I can tell you in this instance we didn't get it in a timely fashion," Shurmur said. "Now, I'm not saying there's any conspiracy here, it just didn't happen."
Defensive coordinator Bill Davis said the coaches in the booth advise Kelly to throw the challenge flag only when they're certain the play should be reviewed.
"We missed that," Davis said. "But again, it was a quick clip, and again, we made a judgment call and we were wrong."
Easy on the boos
Receiver DeSean Jackson said he hopes fans will cheer the team instead of booing at Sunday's game, even though the Eagles have lost 10 straight at home. Jackson said he's not blaming the losing streak on the boos, but added that the team perceives the disapproval.
"We do hear it, and we're out there trying to do everything we can to win games," Jackson said. "So we just need the support, regardless if we're doing good or doing bad."
