PITTSFORD, N.Y. -- Cordy Glenns long-awaited return to practice on Saturday is not an indication that the Buffalo Bills starting left tackle is anywhere close to being ready to play. Far from it, coach Doug Marrone said hours after Glenn passed his physical and was added to the active roster following an undisclosed illness. "Were going to take it very, very slowly," said Marrone, of a player whos been sidelined since training camp opened July 20. "You wont seem him participating in any team (drills) for a while. And well see how he responds, because I really dont know." And Marrone didnt rule out the possibility of Glenn not being ready for the start of the regular season. He instead noted that rookie seventh-round draft pick Seantrel Henderson has so far shown hes capable of taking over the job on an interim basis if necessary. Glenns status has been a big question mark since tests revealed he had an issue, which the Bills have been careful not to disclose. He was placed on the teams active/non-football illness list a few days before camp opened and was limited to light exercises on the sideline. On Saturday, Glenn was at least finally able to take the field after missing the first 12 sessions and two preseason games. He took part in walk-through drills with the starters to open practice, and then worked out individually on blocking techniques after the two-hour session. Glenn would only refer to his illness as a medical issue, and said its too early to determine when hell be ready to play. "Theres still a little bit of time. Right now Im just focused on trying to help the team out and getting back comfortable again," he said. "It was frustrating not being out there with the fellas, but Im just trying to knock the rust off." Selected in the second round of the 2012 draft out of Georgia, Glenn has been the Bills starting left tackle since his rookie season. Aside from Glenns absence, the Bills starting line has been in flux through most of camp with the exception of centre Eric Wood. There are open competitions at both guard spots as well as right tackle. The Bills (1-1) returned to camp in suburban Rochester a day after a 20-18 preseason win at Carolina. Marrone was comparatively more upbeat after his teams latest performance than he was in the days following a 17-13 loss to the New York Giants in the preseason-opening Hall of Fame Game last weekend. Rather than issuing terse, one-word answers as he did on Tuesday, Marrone said he saw progress, particularly on offence and starting quarterback EJ Manuel. "We did some things better," Marrone said. "I was happy with that. I thought (Manuel) did a nice job, gave us some opportunities to score. And weve just got to take advantage of that." The Bills offence still lacks finish. Though Manuel helped the offence gain 126 net yards and six first downs through three series, the Bills managed just a field goal. And that included giving up the ball on downs at the Carolina 2 after running back Fred Jackson was stuffed for no gain on fourth-and-1. Converting on third downs was also an issue. Buffalo converted 2 of 8 chances in the first half, and 4 of 12 overall. "Obviously, its a concern because it affects the way you win," Marrone said. "Those are things that we need to work on and create a high focus in those areas because thats what playoff teams do." NOTES: In five series under Manuel, the starting offence has come away with two field goals despite three drives inside an opponents 20. ...
