The Bills hope to get some answers for their many offensive line questions over the next three weeks during a series of organized team activities.

One player to watch is second-year man Justin Geisinger, a sixth-round pick out of Vanderbilt who has made strong strides under assistant Jim McNally and could wind up as Buffalo's starting center were he to beat out free agent Melvin Fowler.

Geisinger, 6-3, 322, has great versatility. Smart and hard working, he played tackle in college was drafted as a guard but is now working at center where the coaches like his ability to read defenses and make line calls. In the least, any player who can back up all three spots is a great asset.

Duke Preston, a fourth-round pick out of Illinois last year who received more playing time as a rookie, is also in the mix at center. But Preston is also getting a long look at left guard, where he could unseat Bennie Anderson.

MEDICAL WATCH
OL Duke Preston (ankle), WR Roscoe Parrish (hamstring) and FS Jim Leonhard (hamstring), who were slowed by minor injuries during a three-day mini-camp earlier this month, are expected to take part in organized team activities that begin next week.

--LB Takeo Spikes (Achilles') remains on schedule to be ready for summer camp. He's doing light jogging and lifting.
