Jeremy Maclin told Eagles Television Network during Thursday's preseason game that there's "no doubt" he will be in the lineup for the season opener in St. Louis. "Definitely," Maclin continued. "I'll be able to play in the last preseason game if they let me." Maclin has been working to get back in football condition while catching passes from Michael Vick. He's scheduled to resume practicing Saturday, another positive sign. The return of the Eagles' leading receiver is welcome news for Vick, who got little help from his receivers against the Browns.
