ALLEN PARK, Mich. – The Detroit Lions lost both tackles and a guard from last season's regular starting lineup, so there's plenty of opportunity as the franchise ended its first full week of training camp.
Tackle Riley Reiff, a first-round pick in the 2011 NFL draft, is settling into the left end of the line while veteran Jason Fox will form the other bookend after appearing in just one game last season.
Veteran center Dominic Raiola is back for a 13th season and joins guard Rob Sims as the only members of the line to start all 16 games in 2012.
Rookie Larry Warford, free agent Jake Scott and backup center Dylan Gandy all have seen time at the other guard spot.
"Whoever's out there knows what they're doing and knows what we've got to get done," Reiff said Saturday. "Whoever is out there, it's going to work."
