Not sure we'll do this every week, but with the NFL season opening, we'll check in with the seven former USF players on NFL rosters and see how they fared on the opening weekend. USF had 14 former players in NFL camps, but six were cut, with just linebacker Tyrone McKenzie latching on with a practice squad, in New England. Veteran linebacker Kawika Mitchell, who missed 11 games with a knee injury last season, will miss the entire 2010 season after getting placed on injured reserve Friday by the Bills due to a foot injury. Here are the rest:

Nate Allen, S, Eagles: Had a nice center-field interception on a high throw by Packers quarterback Aaron Rodgers in the fourth quarter, helping Philadelphia try to rally late in its 27-20 loss. Allen started at free safety and finished second on the team with five total tackles.

Mike Jenkins, CB, Cowboys: Started at corner and had two tackles and one pass defensed Sunday night in Dallas' loss to the Redskins.

Stephen Nicholas, LB, Falcons: Came off the bench and finished with four tackles and one on special teams in the Falcons' overtime loss to Pittsburgh.

Jason Pierre-Paul, DE, Giants: First-round pick came off the bench and had one assisted tackle, plus one on special teams, in the Giants' win against Carolina.

George Selvie,  DE, Rams: Rookie had two tackles off the bench in his NFL debut, losing a close one to Arizona.

Jerome Murphy, CB, Rams: Was one of eight gameday inactives for Rams -- not sure if that's still due to ankle injury from preseason.

Carlton Mitchell, WR, Browns: Homecoming to Tampa was disappointing as he was a gameday inactive for Browns in loss to Bucs.

And four former Bulls will open their UFL seasons this weekend -- receiver Huey Whittaker and safety J.R. Reed of the Florida Tuskers, receiver Taurus Johnson of the Hartford Colonials and guard Frank Davis of the Las Vegas Locomotives.
